Preface¶

THE PRODUCT¶

This manual describes the second main version of the ND program editor

PED-ENG-J

which is both a fullscreen and a line based program editor incorporating extensive editing functions. Files are entered and edited from a video display terminal or a teletype terminal. On terminals with cursor addressing, the editor will normally be run in page mode. In line mode, PED functions like an extended version of QED. Files can be both program and data files. The Editor will not be able to read NOTIS-WP format (16 bits) files, and the reader is warned that none of the compilers of ND will accept 16 bit format files. Files generated by PED are accepted by all ND compilers.

THE READER¶

The information contained in this manual is primarily intended for users who require a detailed and formal explanation of the product, as well as an account of the features and facilities available to them. As the present product is quite different from previous versions, it will also be useful to those who have used the previous PED editor (E-version and earlier).

PREREQUISITE KNOWLEDGE¶

Although basic familiarity with the principles of electronic word processing, and in particular with the earlier versions of ND Program Editor (PED), is an advantage, the user needs no knowledge of computers or programming in order to use PED. It is also useful to be familiar with the ND operating system, SINTRAN III.

THE MANUAL¶

The present document describes the ND Program Editor PED, and has been written as a combined User Guide and Reference Manual. Appendices A, B, C and D are devoted to error messages, the editor menus, the help structure, and an ASCII conversion table.

AN INTRODUCTION TO PED¶

1 AN INTRODUCTION TO PED¶

1.1 Some comments on notation conventions¶

To make the manual readable some "shorthand" notations are being used. The main notations are:

Notation Description

<x> When occurring in the text it refers to a command performed by holding the CTRL key down while typing the key inside the angle brackets.

&x This is another way of writing a non-writable character. It is not much used in the manual, but is the way PED writes control characters. If PED cannot print a character, a & sign is put instead. Use the <v> command to get the value of character.

yB If y is a number, the B (or b) denotes that this is an octal number (i.e., base 8). This is standard in all ND documentation.

FUNC On NOTIS terminals this is a function lead-in key placed on top of the numeric key pad. To perform this command on a non-NOTIS terminal, you have to input CTRL UNDERLINE (< _ >). (On some terminals underline is a shift character and the command is then CTRL SHIFT UNDERLINE). The ascii value is 378.

⏎ This sign is the marking of the carriage return key on a NOTIS terminal. (ascii 15B) On other terminals this may be marked as "RETURN" or "CR".

⌂ This is the sign on the HOME key on the NOTIS terminal. This may be marked "HOME" on other terminals.

HOME position Topmost left corner of the screen. It is marked with PED:.

NO-60.121.4

Page 15¶

1.2 The Screen¶

PED will use the screen for a number of different purposes. All of them have a fixed position on the screen, so that although much information is displayed, it should be easy to understand. On the NOTIS terminals, some lights (LEDs) are also used to make some frequently used messages more visible.

Line: 1-21 The second command line

Column: 1-80 The tabulator line

......T 1...T

......2......

end.

+d Expand The status line

1.2.1 The text area¶

The text area can be divided into a maximum of 3 windows. Each window shows a part of a named region. See page 15 on what a region is. This feature with several windows is called a split screen. The screen may be divided either horizontally or vertically (not both at the same time). A split screen is defined in Menu no. 1 (the six fields at the bottom) in this way:

Vertical split (all windows occupy 21 lines, but different no. of columns).

Region in window 1 MAIN

Lines.Columns in window 1 21.38

Region in window 2 SOAP-SUBROUTINE

Lines.Columns in window 3 21.20

Region in window 3 SOAP-IO

Lines.Columns in window 3 21.20

NO-60.121.4

Page 16¶

PED User's Guide¶

AN INTRODUCTION TO PED¶

Now the screen will look like this (compressed at the right side):

|─────────────────────────────────────────────────| | Active region | | PED: | | Line:39-59 Column: 1-80 Region: MAIN Position: | | (....T.1...T:....2........T.......(....T.1...T...| | | | | | Tabs etc. for window 1 | Text in region | Text in region | | Text in region MAIN, | SOAP-SUBROUTINE | SOAP-IO | | window 1 | window 2 | window 3 | | Status line .... | | | |─────────────────────────────────────────────────| | Split lines | |─────────────────────────────────────────────────|

Horizontal split: (all windows occupy 80 columns, but different no. of lines). In the example only two windows are used.

Region in window 1 MAIN

Lines.Columns in window 1 11.80

Region in window 2 SOAP-IO

Lines.Columns in window 3 9.80

Region in window 3

Lines.Columns in window 3 0

Now the screen will look like this:

|─────────────────────────────────────────────────| | Active region | | PED: | | Line:39-59 Coloumn: 1-80 Region: SOAP-IO Position: | | (.....T.1...T:....2.......T.......T.......T....| | | | | | Tabs for region SOAP-IO | | | | The text of region SOAP-IO in window 2 | | Status line .... | |─────────────────────────────────────────────────| | Split line | |─────────────────────────────────────────────────|

ND-60.121.4

Page 17¶

1.2.2 The status line¶

The status line is the line in inverse video at the bottom of the NOTIS terminal screen. This line will at all times give the following information, which corresponds to values set in the menus or with the various commands and function keys.

*cd* if alternative delete mode is set.

Verify if verify mode is active.

Append if append mode is active.

Expand if expand mode is active.

1.2.3 The command line¶

The command line is the first line of your terminal if you are in page-mode. The line is indicated by

PED:

This line is also used to display error messages and other messages from PED. Some of the commands use the command line to display parameter input. The right end of the line is used to indicate that file operation is in progress. The display has 10 segments, and indicates how much is done.

| Example |

If you read a file, an arrow moves from left to right one step for each ten percent of the file. After 30% the display looks like this:

--->

1.2.4 The second command line¶

The second command line is the second line displayed on the terminal. It can look like this (a little compressed):

Line: 261-281 Column: 1-80 Region: MAIN Position:

Page 18¶

PED User's Guide¶

AN INTRODUCTION TO PED¶

where:

Line: The numbers displayed are the line numbers within the first and the last line on the screen window.

Column: The numbers displayed are the column numbers of the leftmost and rightmost columns of your screen window. This is normally 80 character positions, and if the first number is different from 1, you are not looking at the leftmost part of your buffer.

Region: The region is the name of your current region. Default is MAIN. The commands for marking areas, or working with marked areas take current region as default region.

Position: Indicates where in the buffer you are, relative to the first and last line. The file is divided into 10 equally-sized parts, and the cross indicates where you are now. Initially, when you start to write a new file, your position is "last" and the indicator is thus placed in the rightmost position.

1.2.5 The tabulator line¶

The tabulator line is the third line of your terminal display, and contains some tabulator and border information. When you first enter PED it will look like this for the first character positions:

(......T.1....T:....2.........T.....:...

(: The left parenthesis is placed in the position of the left border. A right parenthesis is displayed in the position of the right border. See also page 35 on Borders.

.: The dot appears in all positions where there is no other sign.

:: The colon appears every 10th character position, beginning at position 5. It will alternate with a number every 5 positions.

number: The numbers 1,2,3,4,5,6,7,8,9,0 are displayed in the positions 10, 20, 30, ... Mathematically it may be said that the column position is displayed with only the 10's place unmasked.

T: A "T" denotes that a tabulator stop is placed in that position. To learn how to manipulate the tabulators, see page 33.

ND-60.121.4

Page 19¶

PED User's Guide¶

AN INTRODUCTION TO PED¶

A "D" (not displayed as a standard) denotes a secondary tabulator stop.

Only one character at a time can be displayed in a given position. The priority is like this:

Priority Character

6 ( and )

5 D

4 T

3 number

2 :

1 .

The highest number gives the highest priority.

1.2.6 The WAIT message¶

The wait message occurs in the upper right corner of the screen.

WAIT -

It is used to indicate that the command you have given will take some time.

Example:

If you try to read or write a file, PED will ask the file system to open the file. At the same time the message - WAIT - will be displayed. The wait signal is switched off when PED starts the actual reading of the file.

1.2.7 The LED display on the terminal¶

Above the keys on the keyboard of the NOTIS terminals are some red LEDs. (Light emitting diodes) Three of them are used by PED to indicate some status variables. Their meaning is:

EXP or EXPAND

The LED is on when expand mode is on.

INS or INSERT

The LED is on when insert mode is on.

BUSY

The LED is on when PED is doing things that may take some time. This can be when:

PED User's Guide¶

AN INTRODUCTION TO PED¶

Executing a READ/WRITE command

Moving and deleting areas

It is used to notify the user that PED has accepted the command, although the screen is unaltered.

1.3 The command types¶

There are 3 types of commands in PED.

HOME commands

Function key commands

Control key commands

1.3.1 The HOME commands¶

All HOME commands must be given in the screen HOME position, which is marked PED:. You use the K key (HOME) to enter this position. To give the command you only type one character. All one character commands are HOME commands.

A HOME command may be cancelled by pressing the HOME key in reply to a prompt. The GET-STRING, SUBSTITUTE, READ and WRITE commands can be interrupted by HOME.

Many of the HOME commands have one or several parameters. Only the mandatory ones are asked for if you type ⏎ after each parameter. If you want to give values to any other parameter, you have to use the cursor up (↑) or left wide arrow (⟸⟸⟸) to move to previous parameters, and cursor down (↓) or right wide arrow (⟹⟹⟹) to move to next parameter. You can edit the parameters you have input until you input ⏎ to the last mandatory parameter.

1.3.2 The function key commands¶

The NOTIS keyboards have a number of dedicated keys. Most of them have a function in PED. They can be activated both in the text windows and in the HOME position. On non-NOTIS terminals, the function commands are activated by a sequence of keys. Some of the function key commands have equivalent HOME commands.

ND-60.121.4

Page 21¶

1.3.3 Control key commands¶

Control key commands are used to edit text in the text windows and to edit parameters to HOME commands. Some of them have equivalent function key commands.

1.4 How to start the program¶

To enter PED, you give the command:

@PED

Note that this command may have to be given as @PED-ENG or @PED-NOR etc., depending on which language version you are using. The system responds with

PED:

in the HOME position and its identification on the command line of the screen.

1.5 To start a new program file¶

The cursor must first be placed on the first character position of line 1 with the ↓ key (CR) or the ↰ key (HOME). If you are accustomed to earlier versions of PED, you may be used to doing this with the cursor down arrow ↓. This is an option in PED versions later than E, and can be set by a flag in Menu no. 2. See also the chapter on changing PED parameters page 33.

When you have written a few lines, and created the first part of the text for your program, you will usually want to save your text. You will then have to create a file recognized by the file system.

To do this, you move the cursor into command position with the HOME key.

↰

You then create your file, by giving it a name with the W command (WRITE FILE: ""), explained under "Commands for file handling" page 25, and thereby store your file in the computer mass storage memory for further use. If you want to edit an existing file, you may read it into the work area by the R command (see page 19).

ND-60.121.4

Page 22¶

PED User's Guide¶

AN INTRODUCTION TO PED¶

1.6 The PED work area¶

PED has a work area containing the text edited during the current run of the program. This area can be filled with text both from existing files and directly from the terminal. The current text is edited from the terminal by giving commands and data to PED. You can have lines up to 255 characters long, and PED will break the lines if they are longer.

NOTE:

Editing is only done in the work area and does not automatically store the text on a file. It is therefore necessary for you to write the file onto a disk file with the W command before you exit from PED. PED will ask you if you want to store the text if you forget.

1.7 Area¶

In PED you are sometimes asked to input an area. The concept is described here. Formally the definition is:

<region>.<first line>.(first column):<second line>.(second column)

Most of these parameters can be omitted, and PED will use default values when necessary.

Parameter Description

Region Region is an alphanumeric name of a region. A hyphen is accepted inside a name. The region must be known to PED. If you want to create a new region, use double quotes around the name. The region MAIN will always exist. If region is omitted, current region is assumed. Region names can be abbreviated. Regions are described on page 15.

First line The first line to be affected by a command. This parameter can be given as an expression, as all the numeric parameters.

Second line The last line to be affected by a command. If this one is omitted, and the first line is specified, the value given as first line will be filled in for the last line as well.

First column The left margin of the text to be affected by a command. The default value of this parameter is column 1 for all commands.

ND-60.121.4

Page 23¶

PED User's Guide¶

AN INTRODUCTION TO PED¶

Second Column¶

The right margin of the text to be affected by a command. The default value for this parameter is the last possible column (column 255) for all commands.

All¶

All is a predefined area command meaning "the whole current region", and can, f.ex., be used to delete all the text in the current region, while keeping the region name. "ALL" cannot be abbreviated.

1.7.1 Expressions¶

All numeric parameters can be given as expressions. The expressions are evaluated as integer expressions. Therefore a dot is illegal as part of a number, (in fact a dot will be treated as delimiter in area input) and any decimal part due to division will be lost. The expressions are evaluated using 32 bit words. Legal expressions are described under the Value command (page 43) in the chapter on utilities.

PED User's Guide¶

FILE HANDLING COMMANDS¶

2 FILE HANDLING COMMANDS¶

This chapter contains the commands in connection with the file system. The commands are now safer than in previous versions. You are asked if you want your text buffer saved before any command is executed that might corrupt it, or use it for some other purpose. To unfamiliar users, this is preferable. Those with experience with earlier versions of PED will hopefully learn to appreciate it too, as soon as they become accustomed to it.

PED has a work area containing the text edited during the current run of the program. PED uses file 100 as scratch file during editing, and the editor will write out an error message and stop if file 100 is not open. The easiest way to open the correct scratch file is to log out (@LOGOUT), and start anew. PED is able to handle about 40,000 lines, so if you have problems with size, the error is usually that user SCRATCH has no more free space. Contact your System Supervisor to help you. The largest size file 100 that PED can handle is about 6000 pages (á 2000 bytes). You can have lines up to 255 characters long, and PED will break the lines if they are longer. This will be marked by a “$” in column 1 of the broken line. See the command SET/RESET LF/CRLF AT END OF LINE page 50.

2.1 Regions¶

The regions are a new feature in PED, and utilized, it will make life a lot easier for programmers using multiple sources, text and list files. A region is a named area in the editor’s work area, and you can have a maximum of about 40 regions in PED at a time. The first time a name is referenced, it has to be created by placing double quotes around the name.

Example:

||| |---| | “SOAP” |

The first character in a region name has to be an alphabetical character. In the read command (page 19) you can specify a region when asked for INSERT BEFORE:. If you want to read the file SOAP-MAIN into the region SOAP, it will look like this:

Example:

||| |---| | PED:Read file: |

| Insert before: “SOAP” |

Now the whole SOAP-MAIN is read into your region SOAP. If you do not specify any region, the current region is used. To move between regions you use the home command move (M), and specify region name when asked for “Move to position:”. It is also possible to copy to another region, and in all the copy area/move area/delete area

NO-60.121.4

Page 27¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

commands, a region name is accepted as an area, or as part of an area specification.

Example:

Delete area:soap.1:200

will delete the 200 first lines of the region SOAP.

If you are using the MARK or FIELD keys to mark text, the region is implicit, so that you can mark an area in one region, move to another, and then copy or move the text you marked to that area, just as you would do inside a region.

2.2 Commands to PED in a file¶

On the first line in a file you can write commands to PED. These commands are read by the editor when you read a file into your input buffer. The commands are:

2.2.1 Tabulator - TAB¶

The tabulator command is equivalent to the home command T, and is described in the chapter on changing the PED parameters. { page 33 } The command is initiated by the letters TAB, and space is used as separator inside the command.

Example:

C TAB S3 5

The TAB command starts one or more spaces after the comment sign, and will order PED to set tabstops beginning in column 3 with a tab for each fifth column up to column 255. If you set a plus sign "+" or a space in the character position immediately behind the TAB, tabulator marks (ctrl I [ASCII 118]) will be expanded on input. If you do not want to have your tabs expanded as in a print file with commands to a printer, you input a minus sign "-" after the TAB command. For full description of the tabulator command, see page 33.

ND-60.121.4

PED User's Guide¶

FILE HANDLING COMMANDS¶

2.2.2 Borders - ()¶

The border command is started by two parenthesis like this "( )", with a normal border command following. For a full description of the border command, see page 35.

Example:¶

C ()5:80

This will set the left border to 5 and the right border to 80.

All non-blank characters from position 1 are reserved for the beginning of a comment. This will prevent the compilers from reading the PED commands. Comments can be:

Character Language

C Fortran

! MAC, NPL and Planc

* Cobol

(* and { Pascal

or whatever you like that your subsystem will accept as a comment.

The commands are separated by a semicolon ';', and can be combined in setting both borders and tabulators. The tabulator command has to be input first. If you want to write more on the same line you also have to terminate the last command to the editor with a ';'. Multiple spaces are accepted as one. The lines below will all give the same response from PED.

Example:¶

C TAB F;() 7:72 C TAB F : () 7:72 C TAB F ; () 7:72 Ctext tab f;() 7:72; more text

This will set tabulators to standard FORTRAN, left border to 7 and right border to 72.

Page 29¶

2.3 Commands to PED from the SINTRAN command line¶

Commands can be given to PED from the SINTRAN command line. They are given as normal commands, specified with parameters separated by space or comma. A semicolon terminates a command. If a command terminates due to an error, the rest of the commands will be skipped.

Example:¶

To start PED with SOAP-MAIN in region MAIN, SOAP-IO in region IO, and SOAP-SUBROUTINE in region SUB, this is how to write it:

@PED SOAP-MAIN;R SOAP-IO "IO";R SOAP-SUBROUTINE "SUBR";

PED will now:

1) read SOAP-MAIN into region MAIN (default region)
2) read SOAP-IO into region IO
3) read SOAP-SUBROUTINE into region SUBR

Your current region is now region SUBR.

Example:¶

If you want to have the PASCAL compiler as your exit program, and start editing in line 250 in the file SOAP-MAIN you can do it this way:

@PED SOAP-MAIN:1,,,PASCAL:; 250;

PED will now:

1) read SOAP-MAIN into region MAIN (default region)
2) go into Menu no. 1
3) write the text "PASCAL" in the third line (the Exit Program Name)
4) The semicolon returns to home position, ready to accept more commands.
5) The "enter position" command is executed.

PED will now display the lines 245-265 with the cursor in column 1 in line 250.

ND-60.121.4

PED User's Guide¶

FILE HANDLING COMMANDS¶

2.4 Read file - R¶

The R command will cause text to be fetched into the PED work area from a file which has already been edited and written in the computer's memory.

R

The basic format of this command is:

Read file: <file name>

As you can see, <file name> is the only mandatory parameter in this command and if you give this parameter alone followed directly by ↵, your whole file from the first to the last line will be fetched into the work area. If no (DIRECTORY:USER) is specified in the file name, PED will assume that you want to read a file under your own user, and will put in empty parenthesis in front of the file. This will prevent the file system from looking for your file under user SYSTEM.

But you also have the possibility to fetch only a part of the file into the work area, by specifying the optional (from line), (to line) parameters.

The format of the command is then:

PED:Read file: <file name>

Insert before: ↵

Area: <from line>:<to line>

Example:

PED:Read file: SOAP-MAIN

Insert before: ↵

| Area: 25:250 ↵ |

Only lines 25 through 250 of your file 'SOAP-MAIN' will then be fetched into the work area. This is useful if you want to use parts of a file only since you can choose either to create a separate file with these few lines by giving it a new name or to shorten your current file because you are no longer interested in the rest of it.

The abbreviation will be carried out if you write lines 25 through 250 of your file 'SOAP-MAIN' in the computer's memory under the same name 'SOAP-MAIN', because the lines before line 25 and after 250 will then be erased and only lines 25 - 250 of 'SOAP-MAIN' will remain. Although you have fewer lines in your file now, the size of the file in pages seen from the file system is not reduced. To reduce that size, you will have to delete the old file and create it anew.

NO-60.121.4

Page 31¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

See the section devoted to the W command - Write current text to <file name> or to <"file name"> { page 25 }

The R command also provides the possibility to merge a new file (or parts of it) into the file you are currently editing, i.e., to fetch more text from another file while you are working on the current file.

You can also decide exactly where you want the additional text inserted.

You then give the R command a second time, in this manner:

PED: Read file: <second file name> Insert before: <line number> Area: <from line>:<to line>

Example:

PED: Read file: SOAP-SUBROUTINE Insert before: 250 Area: 300:600

You have now borrowed 300 lines of text from your second file, SOAP-SUBROUTINE, and you have inserted these 300 lines before line 250 of your current file, SOAP-MAIN.

You can also decide that you want the text inserted in another region than the one you are in.

You then give the R command a third time, in this manner:

PED: Read file: <second file name> Insert before: <region>

Example:

PED: Read file: <SOAP-SUBROUTINE> Insert before: "SUBR"

You have now placed the second file SOAP-SUBROUTINE in the region SUBR. The region has to be surrounded by double quotes if it is not defined already. You will now have two files in PED: the SOAP-MAIN, and the SOAP-SUBROUTINE. The regions can be listed by the X command. { see page 50 }

ND-60.121.4

Page 32¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

It is also possible to use the <V> command to give the line number as the parameter to the prompt Insert before:. If you have used the <V> in the text, you can write ⊥J as response to the prompt, and the line number will be displayed with the cursor placed after the last number. You can then edit the number, or accept it by another ⊥J. The <V> command is described on page 47.

Note that when you fetch a second, complete file into the same region with this second R command, your command will result in one or more of the following prompts from PED:

Save edited text to <default file name> (Y/N)¶

This prompt occurs if you have modified something in your file before giving the second R command, and avoids your losing text that has not been written back to the computer's secondary memory yet.

The text is modified! Do you want to store it (Y/N)?¶

If there is text in the work area but no <default file name>, the system will give this prompt and refuse to carry out the READ FILE command. The question has to be answered with Y or N before the READ command be executed. Type HOME to abort the command.

Do you want to clear current text before reading new file? (Y/N)¶

The prompt requests a confirmation that you really want <current file name> and <second file name> in the work area together.

If you reply YES your <current file name> will disappear from the work area. If you reply NO, it will remain in the work area when <second file name> is fetched.

Update the default file name to <second file name>? (Y/N)¶

The prompt requests confirmation of the default file name. The options are either to answer NO and thus maintain the <current file name>, or to reply YES and rename the merged files to the <second file name>.

In all these READ and MERGE options the default values used by PED, whenever you simply type ⊥J after <file name>, are:

INSERT BEFORE: after the last line in the current region

AREA: the whole file.

ND-60.121.4

Page 33¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

Some of the other subsystems on ND computers recognise special file types. PED will test for some of them on input if you do not specify something yourself. Listed are the file types in order of priority.

SYMB - Standard symbolic files.

PLNC - The ND Planc Compiler.

PAS - PASC is preferred by ND Pascal Compiler.

FTN - The FTN FORTRAN Compiler.

FOR - The ND-FORTRAN-100 Compiler.

COB - The ND COBOL Compiler.

NPL - The Nord PL Compiler.

MAC - The ND 10/100 Assembler.

ASM - The ND 500 Assembler.

BAS - The ND Basic Compiler.

MODE - For MODE files.

DATA - Only "symbolic" data files.

LIST - Preferred by many users for compiler listings.

TEXT - Text files in 7 bit format only.

It is possible to abort a READ command with ⊥ (home). PED will then ask:

Do you really want to abort the read operation (Y/N)?

If you answer N, the read operation will continue.

If you answer Y, PED will write out a message like this:

82 lines read (2048 bytes) (aborted)

or

Search aborted at line number -1

The last message is given if ⊥ is input while the WAIT message is displayed. ⊥ will only interrupt the READ if it was the first character input after the ⌞ terminating the READ command.

Page 34¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

2.5 Update file - U¶

The Update command is a command to read a file into the work area. This command will prevent other users' access to the file while you are working on it. This is valuable if several programmers work on the same set of source files. It will also inhibit you from working on the same file from two terminals at the time. If you try to update several files, the last is the only one with that protection, and you should therefore not try to update several files at a time.

![U]

Pressing the character U will activate the update command, and PED will respond with

Update file:

You then respond by

Update file: < file name >⟨⏎

There are no other parameters to this command.

2.6 Recover buffer - PED ∂¶

If you by accident are aborted from PED, or exit PED without saving what you intended to save, all is not lost. If you have not used file 100, you can write

∂PED ∂

to SINTRAN. The "commercial-at" commands PED to not initiate the scratch file, but rather look for what it left in the scratch file when it was last terminated. If file 100 has been used for something else, the error message:

"MAIN" not found

will be written on the screen, and PED will terminate.

How often the scratch file is equal with your work area is determined by the parameter

Updates before save:

in Menu no. 2. If this parameter is <= 0, the recover buffer command is useless, and PED will usually start with an empty buffer, or some rubbish. If the parameter is positive, a counter is incremented each time an internal function is called. This function is called each time

ND-60.121.4

Page 35¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

You move to a new line, at least twice if you edit a line, and at least three times if you insert a line. When the counter is equal to the value set, the buffer is flushed out onto the scratch file. The buffer is also flushed when:

A REAO command is performed.

A move to another region is performed.

An Exit command is performed.

The buffer is expanded so that an index block has to be split.

The command (∂PED ∂) will save all your regions if the machine stops, or if you by accident managed to start another program not using the scratch file.

You are warned that the editor will have quite a lot to do if you set the number to a small positive number. It will appear slower than if the number is negative, but this is a question of safety. A value of at least 100 is recommended, and if your system is stable and has many users, an even higher value should be chosen.

If you have not used any programs after you last used PED, it may be possible to restart PED by the SINTRAN command

∂CONTINUE

This will only work if you have not been logged out, but if so, it is better than using the ∂PED ∂ command.

2.7 Read file to "number of pages" - R+¶

If you have managed to copy a small file onto a big file by mistake, it is possible to save the last part of the file with the

Read: +

command. The + indicates to PED that it shall read beyond the max-byte-pointer, and read the number of pages as noted in the index table of the file. This will give you an average of 1k byte of rubbish at the end of the file, but this is easily deleted in PED. Remember to write the file so that the max-byte-pointer is set correctly. This command is most valuable if you have managed to copy (∂COPY) the wrong way to a spooled device. You will usually not have read access to the file, so no data is lost. Only the max-byte-pointer is reset, and if you try the read +, you will get all your text back.

Example:

You have copied a line-printer file onto your file with the command

∂COPY SOAP-MAIN:SYMB,LINE-PRINTER,∂

ND-60.121.4

Page 36¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

The command ØFILE-STATISTICS gives the answer that the file SOAP-MAIN is empty:

ØFILE-STATISTICS SOAP-MAIN:SYMB,↓ OUTPUT FILE:↓

FILE 117 : (PACK-ONE:SOAP-USER)SOAP-MAIN:SYMB;1
(INDEXED FILE)
PUBLIC ACCESS : READ
FRIEND ACCESS : READ, WRITE, APPEND
OWN ACCESS : READ, WRITE, APPEND, COMMON, DIRECTORY
OPENED 2 TIMES
CREATED 01.08.55 APRIL 7, 1983
OPENED FOR WRITE 01.09.18 APRIL 7, 1983
4 PAGES , 0 BYTES IN FILE

You then use PED like this:

ØPED +SOAP-MAIN,↓

and when the file is written back, the

ØFILE-STATISTICS,SOAP-MAIN,↓

command gives this answer:

FILE 117 : (PACK-ONE:SOAP-USER)SOAP-MAIN:SYMB;1
(INDEXED FILE)
PUBLIC ACCESS : READ
FRIEND ACCESS : READ, WRITE, APPEND
OWN ACCESS : READ, WRITE, APPEND, COMMON, DIRECTORY
OPENED 4 TIMES
CREATED 01.08.55 APRIL 7, 1983
OPENED FOR READ 01.13.21 APRIL 7, 1983
OPENED FOR WRITE 01.13.21 APRIL 7, 1983
4 PAGES , 7354 BYTES IN FILE

2.8 Write file - W¶

The Write command will cause text to be written from the PED work area into a file.

| W |

Pressing the character W will activate this command, and the following text will appear in the screen home position.

PED:Write file:

ND-60.121.4

Page 37¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

The format of the answer is:

Write file: <file name>

where:

<file name> is the name of the file to be written.

You then write the whole file with name <file name> into the computer's disk storage.

Or

Write file: <file name>

AREA: <area>

where

AREA: <area> is the portion of the text in the work area that you wish to write to the file in the computer disk storage with name <file name>.

The area format is: <region>.<from line>:<to line>

Defaults are:

Parameter Default

region Your current region as indicated in line two on the screen.

from line 1

to line last line of the region specified.

It is not always necessary to indicate AREA; when you wish to write the whole file with name <file name> in the computer's memory you can leave this parameter out and simply give ↓ after <file name> instead of the ↓

If you get the message: <FILE NAME> NO SUCH FILE NAME from PED, just input <W>, and you will get the command back for editing.

PED only accepts ↓ as default file name. * will not be accepted, as it was in previous releases of PED.

A new file name must be given in double quotes when you want a file created for the first time with a Write file: ("<file name>").

You can create it either with the first Write file command, in which case it will also be set in Menu no. 1 at the same time, or by setting it yourself: ("<default file name>") in Menu no. 1 when you enter PED to start the editing of a new file.

ND-60.121.4

Page 38¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

Example:¶

Write file: <SOAP-MAIN>

results in the whole file named SOAP-MAIN being written, whereas

Write file: <SOAP-MAIN>
AREA:1:50

results in only lines 1 to 50 being written.

Example:¶

Write file: <"SOAP-FILE-IO">
AREA:20:150

In this example we have decided that we want to create a file called 'SOAP-FILE-IO' and Write lines 20 - 150 of our current text in this file.

In the upper left corner of the screen the word Writing: will appear, and in the upper right corner a position arrow indicating how far the Write has progressed. Once the required number of lines have been written in the file, the reply n LINES WRITTEN (m bytes) will appear in the upper left corner.

It is possible to interrupt the WRITE command with ⎇. If you input ⎇ while PED is writing a file, PED will stop and ask:

Do you really want to interrupt the write operation (Y/N)?

If you answer N, the write operation will continue. If you answer Y, the write operation is aborted, and PED will write:

xxx lines written (yyy bytes) (aborted) - OUTFILE IS INCOMPLETE!

If you manage to interrupt the write operation while the wait message is on, the message will be:

search aborted at line number -1

In this case no text has been written, and the text on the file you were writing to has not been changed. ⎇ will only interrupt the WRITE command if it is the first key typed after the ^J terminating the WRITE command.

ND-60.121.4

Page 39¶

FILE HANDLING COMMANDS¶

When you Write text in the computer's memory under a name which is different from the <default file name> already set, PED will ask:

Update default file name to SOAP-FILE-IO:SYMB Y/N¶

It is asking you to confirm that you do not want this text to be called SOAP-MAIN, but that you want to name the new file SOAP-FILE-IO.

If you answer Y, the new file named SOAP-FILE-IO:SYMB is set to default file name in Menu no. 1. You will thus suddenly be working on the text of a file called SOAP-FILE-IO and no longer on SOAP-MAIN. On the other hand, your original file SOAP-MAIN remains intact in the computer’s memory.

If you answer N, the process is reversed: you will still be working on the text of your file SOAP-MAIN, but you will have created a new SOAP-FILE-IO file with the same text. Hence, you never lose any text by writing text to a new file name.

In either case you find yourself with two files which can be fetched into the work area separately with the R command, each under its own name:

a) your original SOAP-MAIN file

b) a new file called SOAP-FILE-IO, containing 130 lines of text borrowed from the SOAP-MAIN.

Be aware that if you write only a part of your current file SOAP-MAIN in the computer's memory again under that particular name, you will lose the part of the text that you do not write. This is therefore a way to shorten a file. This will not reduce the number of pages on disk that the file will occupy.

Some examples¶

1) Write file:<file name>

The file <file name> must already exist, and the full contents of the PED work area will be written to it.

2) Write file:<"file name"> | AREA:10:140

A file with the name <file name:symb> is created, and lines 10 through 140 from the PED work area are written to this file.

Page 40¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

3) Write file: <file name> AREA:20,

Only line 20 of <file name> is written.

4) Write file: <file name> AREA:<region name>

The text in region <region name> is written to the file named <file name>.

5) Write file: <file name> AREA:20:$

All the lines from line 20 onwards from your current region are written into the file.

6) WRITE FILE: and another

Write all the lines from the PED work area under the <default file name> which has been set either with a previous READ FILE or WRITE FILE command, or in Menu no. 1.

Before any Write to the default file is carried out, the default file name is displayed, and must be confirmed by pressing once again.

2.9 Append file - A¶

| A |

The append command is a command to append the work area at the end of the file specified. If you use the down arrow (↓) after you specify the file name, you can specify area as in the Write command.

2.10 Exit from PED - E, EXIT, FUNC¶

When you have finished your work in PED, and stored your file text in the file named <file name> again, press:

| EXIT | or FUNC | # |

This will terminate PED, and return to SINTRAN. The command will ask you if you want to save what you have edited, if you have not already done so. For an extensive explanation see page 52.

2.11 Activate PERFORM - FUNC $, SHIFT + EXIT, C¶

The subsystem PERFORM can be activated from PED by the following commands:

ND-60.121.4

Page 41¶

PED User's Guide¶

FILE HANDLING COMMANDS¶

SHIFT + EXIT or FUNC $

The command activates a program called PERFORM, which is a SINTRAN Utility Program. When used, PED will terminate, and will ask you to save all edited regions. For more information see page 53.

2.12 Activate the Text Formatter NOTIS-TF - SHIFT + PRINT, FUNC * .¶

SHIFT + PRINT or FUNC *

The command activates NOTIS-TF with your current default file, unless the main file-name is specified in Menu no. 1. Then the main file is used. PED will terminate, and will ask you to save all edited regions. For more information see page 54.

CHANGING PED PARAMETERS¶

3 CHANGING PED PARAMETERS¶

These commands are used to set a number of editor variables, such as input limits and tabulator marks. These include those marked on the status line, and those found in the menus.

3.1 Set new tabulator stops - T¶

The T command enables you to set tabulator positions at your own choice. See also the TAB function key in the next section.

The format of the command is:

T

TABULATORS: <position-1>,<position-2>,....<position-'n'>

where the <position-number> is a number between 1 and 255, in increasing order.

The following may be specified as <position>:

C for COBOL
Tabs = 8, 12, 16, etc. ....... max. 255

F for FORTRAN
Tabs = 7, 11, 15, etc. ....... max. 255

L
Tabs = 4, 7, 10, etc. ....... max. 255

M for MAC
Tabs = 8, 14, 30, 40, etc. ....... max. 250

P for PLANC/PASCAL
Tabs = 5, 9, 13, etc. ....... max. 255

T for Text
Tabs = 9, 18, 27, etc. ....... max. 250

for No tabulators i.e., clears all tabstops.

The increment may be altered by specifying <increment>, i.e., <position,increment>. Thus, <T,5> results in tabulator positions 9, 14, 19, 24, etc.

Page 45¶

PED User's Guide¶

CHANGING PED PARAMETERS¶

An eighth possibility is to specify:

S for Special

S has two parameters: the ⟨first position⟩ and the ⟨increment⟩. This may be added to a list of positions, e.g., if you want tabulators in the positions: 5,7,13,20,30,40,50,60,70,..., the quick way of writing this is to input the irregular tabs (5,7,13) succeeded by an S command: S,20,10 like this:

Tabulators: 5,7,13,S,20,10

They are at all times marked on the dotted line (third screen line) together with the ( ) indicating the borders. Default tabulator setting is MAC setting (M).

3.2 Set/reset tabulator positions here - the TAB key, FUNC TAB, FUNC , FUNC ¶

With the tabulator key:

TAB or FUNC TAB or FUNC

+ or FUNC

you can set and reset tabulator positions for a program or a data file in the character positions of your choice.

Pressing the tabulator key when the cursor is on the tabulator position you want will result in the position being marked with a T on the position line on the screen (the dotted line). Tabulator positions are deleted by pressing the key a second time.

The TAB key is used when the cursor is in the text area.

3.3 Set/reset secondary tabulator positions here - SHIFT + the TAB key, FUNC BTAB, FUNC ¶

You also have a secondary tabulator set, marked by the letter "D" on the tabulator line. To set and reset the tab mark you do as you do with the standard tab set, using the commands

NO-60.121.4

Page 46¶

PED User's Guide¶

CHANGING PED PARAMETERS¶

SHIFT + TAB or FUNC

There is no equivalent HOME command for the secondary tabulator set.

For commands to navigate between the tabstops, see the chapter on navigating commands.

3.4 Set new editor borders - B¶

The HOME command B enables you to set new borders for the text to be entered after the new borders have been set. See also the border functions in the next sections, and the default borders set in Menu no. 2.

B

The format of the command is:

Borders:.

Borders are used to detect the beginning and the end of a line, and to stop the user from unknowingly write program sentences and commands in illegal character positions. It is very useful for a FORTRAN programmer to be stopped at column 72, and some of the ND compilers have also some practical limits not demanded by the language, although they are usually so large that you will probably not know them. A more normal problem is the paper width of your printer. Usually this is either 132 or 80 characters, and this may be useful standard limits.

3.4.1 Set left editor border in this position - ( , FUNC (¶

Pressing the border key:

... or FUNC (

sets the left editor border marked with ( on the dotted line, in the character position under which the cursor is placed when the key is pressed. The border key updates the editor borders set in Menu no. 2. You thus have the possibility of modifying this border if you want a portion of your text to start (and end, too - - see the next command) in another character position than the rest.

while the cursor is in the character position where you want your right editor border to be, this position will be marked ) on the dotted line.

3.5 Set the editor in line mode (QED compatible) -¶

Key Combination Function

SHIFT + #

The command sets PED in line mode (see chapter 9 LINE MODE EDIT), thus making it compatible with programs such as QED (see QED Users Manual NO-60.031). TELETYPE and DECWRITER terminals can run PED in line mode only.

This command is used to change the editor from running in page mode to run in line mode. The command has no parameters.

3.6 Change the terminal type to - !¶

On TOV-2200/9-ND-NOTIS the terminal type is 53, and on FACIT-4420-NO-NOTIS it is 57. To change terminal type, you use the command

TANDBERG TDV-2200/9-ND NOTIS (53)

FACIT-4420-ND NOTIS (57)

These are the terminal types the PED editor can presently be used on. If other terminals are used, contact should be taken with ND to find out if they can be implemented, and what it will cost you. It should not be expected that the user friendliness will be as good as on the NOTIS terminals.

The ! command is meaningless if one is using a terminal without an ability to run in different modes. It may be used if the initial terminal type was wrong, though. The command will cause the editor to reinitiate the screen, eg., some terminals will clear the screen, and reset terminal values to standard.

3.7 Set/reset expand mode - EXP, ¶

Pressing this key:

| INS | | EXP | | <E> |

causes the word EXPAND to appear on the status line. The function enables you to insert new characters in the existing text, before the current cursor position. The expand mode is turned off by another typing of the expand key. The word EXPAND will then disappear from the status line.

Example:

You wanted to write existing, but you made a typing mistake and it came out exiting. You now position the cursor on the t, press the EXPAND key or <E> and type the missing s. The text will open up and make room for the s.

When expand mode is set, a LED marked EXP will switch on, and stay on as long as expand mode is on.

Page 49¶

PED User's Guide¶

CHANGING PED PARAMETERS¶

You can continue to type in new characters in this manner for as long as EXPAND mode is active, and it is thus possible to insert unlimited amounts of new text this way.

To get out of EXPAND mode you simply press the key a second time, and the word EXPAND disappears from the bottom line.

The EXPAND key or respond both in HOME position and in the text.

3.8 Set/reset append mode - INS, ¶

Pressing the same key in shift position or :

SHIFT + INS or

EXP

...causes the word APPEND to appear (or disappear) on the bottom line. The function enables you to insert new lines of text in the existing text, under the current line. The new lines are opened up each time you press ↓. The LED marked INS on the keyboard will be on as long as the append mode is set.

Example:¶

You have written a 10-page program and discover that you have forgotten a subroutine in the middle of it. There is no cause for despair, and you do not have to retype the whole second half of your document. You simply position the cursor on the line above the place in the text area where you want blank lines to be inserted to start editing the forgotten text, press SHIFT and the INS key, or , and give ↓. You will see the text open up and a blank line appear. It does not matter how long the text is that you had originally forgotten; the system will continue to give you blank lines in this manner until you press SHIFT + INS or again to get back into the usual edit mode.

The function responds both in HOME position and in the text.

3.9 Set/reset alternative delete mode - FUNC 🔲, FUNC DEL¶

The

| FUNC ⬜ | or FUNC DEL |

ND-60.121.4

Page 50¶

PED User's Guide¶

CHANGING PED PARAMETERS¶

The command enables you to set/reset alternative delete mode. When alternative delete mode is ON, it leads to the 'A' (but not ) being interpreted in different ways according to prior input. The flag 'ed' is placed on the bottom status line when alternative delete mode is on.

Example:¶

If the cursor is positioned on a character, 'A' deletes the character and contracts the text, as usual.

If EXPAND mode is OFF and you use 'A' while inputting text, the last character input is replaced by a space, i.e., the text is not contracted.

If EXPAND mode is ON, the last character input is deleted.

More information is given on page 83 under A.

3.10 Display Menu No. 1 - 1¶

Pressing the digit 1 while the cursor is in the HOME position brings Menu No. 1: Editor Flags up on the screen (see Appendix B).

Display Options¶

PED supports the following display options:

Description Option

Display line numbers -number

Display tabs as "tab symbols" -tabsym

Display a ruler in the first line -ruler

Highlight and display control characters -ctrl

Display carriage returns as "$" -display

Line Numbers¶

When requested, PED displays line numbers on the left side of the screen. Line numbers are always displayed, regardless of tab symbols, ruler settings, or control character highlights. If disabled, the numbers are hidden until this option is re-enabled.

Tab Symbols¶

When requested, PED displays the tab symbol "→" in place of tab characters. The tab character occupies eight-character spaces if different tab settings are not specified.

Ruler¶

PED supports a ruler to display character positions in the first line. This feature is useful for tracking column positions. The character positions in the file directly correspond to the ruler.

Control Characters¶

Control characters in the text are highlighted and displayed on the screen. This option is useful for spotting non-printable characters or special formatting.

Display Settings¶

Carriage Return Symbol: The carriage return symbol is displayed as the "$" character.

Display Toggle: The display options can be toggled on and off to suit coding and readability preferences.

4.1 Evaluate a numeric expression - V¶

The home command

V

establishes the decimal, octal, hexadecimal and ASCII values of any 32 bits integer expression.

Example:¶

You want to establish the values for the figure 1234567.

You give the V command, and after the system prompt 'Value of:' you input 1234567 as parameter and press ↵.

In the screen HOME position the operation looks like this:

PED: Value of: 1234567 ↵

Is:

Decimal 1234567

Octal 4553207

Hex 12D687

Ascii "&RV\&G"

Generally speaking, all arithmetic expressions are 32 bit integer expressions (-2**31 to 2**31-1). There is no testing of overflow neither in the intermediary calculations nor in the results. A division by 0 is not detected.

T ::= T * U | T / U | T ( U | U

U ::= - E3 | - E3 | F

F ::= abs P | P ** F | P mod F | P

P ::= ( E ) | ID

ID ::= $ | #c | 'chrs' | /string/ | a | number

Explanation of the BNF¶

The explanations refer to the terminating symbols in the BNF. That is: the symbols you are supposed to type.

$: This corresponds to indicating the number of the last line in the current region. In the 'AREA' parameter of the R (retrieve document) command, $ equals 65535.

Example¶

If there are 56 lines, $ will be understood as 56:

PED: Value of: $↓

Is: Decimal 56 Octal 70 Hex 38 Ascii "8"

#c: This corresponds to the internal representation of 'c':

The value of "^(D)" (ctrl D):

Value Representation

PED:Value of: *#0X^(D)

Is: Decimal 27 Octal 33 Hex 1B Ascii "&["

'chrs'

This corresponds to 1 to 4 characters, right justified, in a 32-bit integer. If '' is to be included, it has to be written twice.

Example:¶

If you want to evaluate ab'c, you will have to type it like this: 'ab''c'

/string/

This implies searching for a string in the current region. The search starts at the current line of the current region, and will only find the first occurrence of string. To get the next, you have to move to the line after the value returned from the VALUE command, and then start a new search. The line number is then displayed in decimal, octal, hex and ASCII. Instead of / one may use ! % ? or |.

Example:¶

The input of /begin/ will give the result:

Value Representation

Is: Decimal 104 Octal 150 Hex 68 Ascii "h"

If the first begin in your program after your current line is line 104.

number

This encompasses decimal numbers (0 to 9), octal numbers (0 to 7 terminated by B) and hexadecimal numbers (0 to 9 and A to F, the number is terminated by H and the first digit must be within the range 0 - 9).

PED UTILITIES¶

Example:¶

99 = 99D = 143B = 63H = "c"

10d = 10D = 128 = 0AH = "&J"

17b = 15D = 17B = 0FH = "&O"

0abh = 171D = 253B = 0ABH = "+"

Upper and lower case are equivalent.

-E3 +E3¶

Contrary to usual mathematics, these are not positive and negative numbers. Instead, the editor will add a number before the sign in order to make it an addition or a subtraction. -3 is therefore understood as x-3, where x depends on the context. The number -3 should be specified (0-3). x is equal to 0 in the value command, equal to the line the cursor goes down to when the HOME key is input in all AREA parameters, equal to the line number of the first line on the screen in the M (move to position) command and equal to the old contents of most of the parameters in the menu commands.

Example:¶

If line 30 to 50 are visible on the screen and you give the command M:<-5>, this is equal to giving the command M:<30-5> or M:<25>. In all these events lines 25 to 45 will be shown on the screen.

not¶

Computes the bitwise not operation on the succeeding expression.

Example:¶

PED:Value of: not 100

Is: Decimal -101

Operator Description

xor Computes the bitwise xor operation between the preceding and succeeding expression.

or Computes the logical or between the expressions.

and Computes the logical and between the expressions.

shift Computes a bitwise shift operation on the preceding expression a number of times given by the succeeding expression. Positive number of times gives left shift, negative values give right shift.

abs Computes the absolute value of the succeeding expression.

** The first expression is raised to the power of the second expression.

mod Computes the modulus of the two expressions.

@ Commercial 'at' is a variable containing the last computed result. It can be used in expressions, and is useful if your expression is too long, or too complicated to write on a line.

Priority between the operators is expressed in the BNF table. The last line has highest priority (computed first) and the first line is computed last. This means that the expression 3+45 is calculated as 3+(45) = 23. If one inputs a number just in front of or just after a parenthesis expression without an operator between, * is presumed to be the operator. This means that 3(4+5) = 27 and (4+5)3 = (4+5)3 = 27. 232 is calculated as 2(32) = 2*9 = 512, because the expression F ::= P ** F results in the first link being raised to the expression that follows.

4.2 Verify current cursor position - ¶

The command can be used for three purposes:

It enables you to verify the current cursor position with respect to value, position and line length.

NO-60.121.4

Page 59¶

Example¶

You press <V> while the cursor is positioned on the character X. In the top right corner of the screen, the system now informs you of the line you are on, the column you are in, the total length of your line, the character your cursor is on, and the ASCII value of this character. The format is:

Line Column Length Char Ascii

4456 63 64 X 1308

You will note that the word From: precedes these indications. This is relevant when you use <V> to mark an area of text for use in the HOME commands Delete, Insert, Move and Substitute described in chapter 7.

To mark an area you proceed as follows:

You position the cursor on the line and character position where you want your area to begin, and press <V>. The system displays:

From: Line Column Length Char Ascii

You now position the cursor on the line and character position where you want your area to end, and press <V> again. The system displays:

To: Line Column Length Char Ascii

The text area is now marked and will be 'remembered'. It may therefore be used in one of the HOME commands mentioned above.

To remember whole lines, the <V> must be input on the same character position of the first and the last line of the area you are marking.

If <V> has been used to mark a text area for one of the operations mentioned, no other <V> command nor operations causing renumbering of the lines in your document must be carried out before that particular area has been used for the purpose it was intended for. The line and column numbers 'remembered' would in such a case no longer be correct. If you move to another region, the <V> markings will not mark text in your previous region, but the equivalent area in your current region. We recommend the use of MARK if you want to copy between regions.

ND-60.121.4

Page 60¶

PED User's Guide¶

PED UTILITIES¶

As HOME command, <V> sets/resets VERIFY mode. The word VERIFY appears on the status line while the mode is active. At the same time, the 'Line - Column - Length - Char - Ascii' indications explained above are displayed and the information given for each character every time the cursor is moved.

4.3 Execute a SINTRAN command - ∂¶

It is possible, while editing text in PED, to execute a SINTRAN command without having to exit from the editor. To do so, you press:

∂

However, there is no check performed on the SINTRAN command given, and if this is not an actual command, such as LIST-FILES, but a valid :PROG file or reentrant system name, then this system will be run, and you will exit from PED and lose PED text that has not been stored with a W command.

Other strings may cause SINTRAN to stop PED. If this is the case, i.e., if the ∂ suddenly appears, you may use the SINTRAN command:

∂CONTINUE

to reenter PED without losing any of your current text.

Example:¶

You are editing text, and need to check some names of other files to be referred to.

Go into HOME position and press ∂.

The prompt SINTRAN COMMAND: appears in the screen HOME position.

Give the SINTRAN command: LIST-FILES

The system responds by blanking the screen and with the acknowledgement: EXECUTING; LIST-FILES

Once you have found what you wanted, you press the space bar, and your screen of text is restored. It is thus unnecessary to exit from PED.

ND-60.121.4

Page 61¶

4.4 Set/Reset LF/CRLF at End of Line - FUNC LF¶

FUNC +

This command is used to set/reset LF/CRLF at the end of file. This can be useful when you want to alter a file that had for some reason lost CRLF/LF, or was transported from some system using another "end of line" marker than CRLF.

Symbol Description

$ A missing CRLF on input is marked by a 'S' in the first character position of the broken line. This will occur if the input line is longer than 255 characters.

+ A missing LF is marked with a '.' in the first character position. This means that on output to a printer, the next line will be written upon this line.

The character in the first character position will not be displayed, but is not lost, and can be examined by <V>.

The command sets the flag in circles when used repeatedly.

no LF no CRLF . S ^ ^ | | +-------+ CRLF on SPACE

4.5 Display Regions - X¶

The home command

X

will clear the screen, display all region names, the size of each region and the SINTRAN filename, and whether the region has been changed. An arrow (+) will point at the current region. The display will look like this:

ND-60.121.4

Page 62¶

PED User's Guide¶

PED UTILITIES¶

Region Lines Modified Default file

MAIN 1435 Y SOAP-MAIN:SYMB

SUBROUTINE 548 N SOAP-SUBROUTINE:SYMB

*FILE-IO 356 Y SOAP-FILE-IO:SYMB

Here we have 3 regions, your current region is FILE-IO, and you have made some changes in that region. You have also made some changes in region MAIN. If you do not specify a region name in the READ-FILE command, YOUR file is read into current region. Region MAIN will always exist, even if you do not use it, and it is the region you will see displayed when you start PED from SINTRAN.

If the list of regions is so long that it will not fit on the screen, PED will prompt:

PED: More (Y/N)?

The answer Y will make PED display another portion of the list until all regions are displayed.
The answer N will make PED return to HOME, ready to accept new commands.

4.6 Re-display the whole screen - space bar, FUNC a¶

Pressing the space bar on your keyboard from HOME position will redisplay the current window. If you are down in a text window, the command

FUNC a

will have the same effect. The function is useful, for instance, if a broadcast is received on the screen during editing and ‘scrambles’ your text. This happens quite frequently when a computer is used by a large number of people for many different purposes.

4.7 The HELP function -- H, ?, HELP, FUNC ?¶

By pressing the HELP key on a NOTIS terminal, or by giving the HOME command H, (the equivalent command on non-NOTIS terminals is FUNC ?) you get access to the lists of available commands and functions in PED. These HELP lists will be different, depending on whether you are working from a NOTIS terminal, or not.

Home commands:

H or ?

The function key commands:

HELP or FUNC ?

ND-60.121.4

Page 63¶

PED User's Guide¶

PED UTILITIES¶

Navigate through the HELP lists with the cursor keys:

| ← | → | ↓ | ↑ |

or by calling the lists up on the screen individually with the aid of the number keys, as explained in the online HELP information. An overview over the HELP structure is given in appendix D.

Due to the diversity of characters that exist on the keyboards in use in the various countries where PED is run, commands as given in this manual may in certain cases not conform with the characters on your particular keyboard. To find the correct key you may have to consult an ASCII table for your keyboard, and compare it to the ASCII table in appendix D.

4.8 Exit from PED - E, EXIT, FUNC¶

When you have finished your work in PED, and stored your text in the file called <file name> again, press:

| EXIT | or FUNC | # |

If you are in HOME position you can also use the direct command:

| E |

As in the READ FILE command, the system will prompt

Save edited text to <DEFAULT-FILE> (Y/N)?

if text has been added or changed after you last saved it with a WRITE FILE command.

If you have typed some text into the buffer without creating a file, PED will not accept the EXIT command and will give a warning and demand an answer:

The text is modified! Do you want to store it (Y/N)?

ND-60.121.4

Page 64¶

PED User’s Guide¶

PED UTILITIES¶

This question will have to be answered with Y or N! To return to COMMAND position you can input HOME:

[ ]

For each region you have changed, PED will ask if you want to write it back to file.

The system will confirm the exit with an erase-page and the text:

PED: EXIT ND Program Editor a

4.9 Activate PERFORM - FUNC $, SHIFT + EXIT, C¶

The subsystem PERFORM can be activated from PED by the following commands:

Command Button

SHIFT + EXIT

or FUNC $

or the home command

[ C ]

The command activates a program called PERFORM, which is a SINTRAN Utility Program. When this command is given, the system will respond with:

Activate: PERFORM,.\ <current file-name>

The command activates PERFORM with your current default file, unless the main file-name is specified in Menu no. 1, in which case the main file is used instead.

The PERFORM starts when you confirm the response with a:

Activate: PERFORM,.\ <current file-name>a

It is possible to edit the command string before starting the perform subsystem with the a. The relevant changes are:

The first parameter after the perform call is default macro file PERFORM-LIBRARY:MCRO. If you want a macro on another macro file, the name of that file has to be input between the two comma signs.

ND-60.121.4

Page 65¶

PED User's Guide¶

PED UTILITIES¶

The \ will be interpreted by PERFORM so that it will ask for a macro name. You may therefore substitute it with a macro name. PERFORM will then not ask for a macro name, but use the one you input.

If the file displayed is not the one you wanted to use in the PERFORM macro, it can be changed.

When you type J the whole line is used as a command to the PERFORM system.

If you try to activate PERFORM without having stored all the edited text with a W command, the system will prompt:

Save edited text to (Y/N)?

The command transfers control from PED to PERFORM. PERFORM will ask you some questions, create a mode file and execute it. It is also possible to activate PERFORM directly from SINTRAN. For more information on the PERFORM subsystem, see the SINTRAN III Utilities Manual ND-60.151.

4.10 Activate the Text Formatter NOTIS-TF - SHIFT + PRINT, FUNC . J¶

The Text Formatter NOTIS-TF is described in NOTIS-TF Reference Manual - Text Formatter ND-63.007. With the PRINT key in shift position, you activate the Text Formatter NOTIS-TF.

SHIFT + PRINT or FUNC .

or the home command

| J |

When this command is given, the system will respond with:

ACTIVATE NOTIS-TF-xxx-J (current file-name)

'xxx' means the language version of the Text Formatter, and 'J' indicates the version number.

The J command activates NOTIS-TF with your current default file, unless the main file-name is specified in Menu no. 1, in which case the main file is used instead.

NO-60.121.4

Page 66¶

PED User's Guide¶

PED UTILITIES¶

The formatting starts when you confirm the response with .J:

ACTIVATE NOTIS-TF-xxx-J <file-name>.J

If you try to activate the NOTIS-TF without having stored all the edited text with a W command, the system will prompt:

Save edited text to <file-name> (Y/N)?

The command transfers control from PED to NOTIS-TF. Once the formatting is done, the system automatically enters INSPECT mode in NOTIS-WP where the formatted document can be scanned for accuracy. It is not possible to return directly to PED from NOTIS-TF. For information on the INSPECT mode, see NOTIS-WP REFERENCE MANUAL - EDITOR ND-63.002.

If you want to format a file with another name than main/default <file-name>, it is also possible to call NOTIS-TF up directly from SINTRAN. See the NOTIS-TF Reference Manual - Text Formatter ND-63.007.

Creating and Initializing Poured Fields¶

After pouring a field, you must also initialize it. The table below summarizes how the INT, EST, and CLOCK commands can be used together to create and initialize a poured field.

Action Command

Pour a new field POUR FIELD

Initialize integer or clock field INT

Initialize estimated value field EST

Pour a specific kind of field POUR <field-type>

Types of Poured Fields¶

Integer Fields

Use the INT command to initialize an integer field after pouring it.

Estimated Value Fields

Use the EST command for fields that hold estimated values.

Clock Fields

The CLOCK command initializes fields that track time-related data.

Example Sequence¶

Pour the field:

POUR FIELD

Initialize the field:

INT (for integer field)

Start using the field as needed.

KEYS USED TO NAVIGATE¶

5 KEYS USED TO NAVIGATE¶

5.1 Move the cursor one line up - ↑¶

Pressing the up-arrow:

[↑]

will move the cursor up one line, i.e., to the current character position but on the line above. If the up-arrow is used in "HOME" position, the window is scrolled a number of lines according to the value of the parameter "vertical step in I" in Menu no. 1 and the number of lines in your current window. If the arrow is pressed repeatedly in a quick sequence, PED will compute how many lines you want to go, and only display the final window.

5.2 Move the cursor one position to the left - ←¶

Pressing the left arrow:

[←]

will move the cursor one character position towards the left.

In "HOME" position this command will move the window a number of columns to the left determined by the width of your window, and the "horizontal step in I" parameter in Menu no. 1.

5.3 Move the cursor to and from HOME position - HOME key or slanted arrow¶

Pressing the slanted arrow:

[\]

Page 71¶

PED User's Guide¶

KEYS USED TO NAVIGATE¶

will move the cursor to the HOME position in the upper left corner of the screen.

If the cursor is already in HOME position when you press this key, your command will move the cursor back to the character position it was in when you last moved it HOME. If you have not used this region earlier, or used a first-page command, the cursor will be placed on the first line in the first column displayed.

5.4 Move the cursor one position to the right - ➜¶

Pressing the right arrow:

| ➜ |

will move the cursor one character position towards the right.

If the command is used in "HOME" position, the window is scrolled "horizontal step in I" of the width of the window, to the right.

5.5 Move the cursor one line down - ↓¶

Pressing the down-arrow:

| ↓ |

will move the cursor one line down, i.e., to the current character position but on the line below.

In "home" position the command will scroll the current window ("vertical step in I" number of lines in window) down. If repeated quickly, the number of entries are counted, and only the first, second and last window are displayed.

5.6 Move the cursor down five lines - LF¶

Pressing the arrow with the three bars:

ND-60.121.4

Page 72¶

PED User's Guide¶

KEYS USED TO NAVIGATE¶

or <J>

will cause the cursor to move five lines down. This is a quicker way of moving than pressing the ↓ key five times.

The key can be used both in HOME position and in the text. On some terminals, this key is marked with LF, LINE or LINE FEED.

5.7 Move the cursor to the left margin on the next line - ↵ CR, RETURN¶

Pressing the ↵ key

| ↵ | or | CR | or | RETURN | or | <M> |

will cause the cursor to move down to the first character position on the next line, or if left margin is set, to the left margin on the next line.

If append mode is active, the key will also cause an empty line to be inserted below the current line.

5.8 Move to the first character on the next line - FUNC ↵, FUNC ¶

Pressing the next line key:

| ⇓ | or FUNC | ↵ | or FUNC | <M> |

will cause the editor to be placed on the first character position of the next non-empty line in the region. If you are at the end of the current region, the next line command will stop at the line after the last line already used. The command is most useful if you are editing heavily indented programs.

ND-60.121.4

Page 73¶

Example¶

If you have some program code with a lot of indentation, it may look like this

1 begin 2 a := 1; 3 while a > 0 do 4 begin 5 if (x + y) = 1 then 6 begin 7 if z * r then a := 0 8 write (output, 'big test'); 9 end; 10 end; 11 end;

In this program the cursor is placed in PED in line 3, and then the

+--------- | C +---------

is activated. The new position of the cursor is determined by the first non-space character position in the next non-blank line. In this example this is the first character on the 4th line.

5.9 Move the cursor to the previous tabulator stop - |<--, , |¶

Pressing the lower left arrow on the arrow pad:

+---- | |< +----
or <Y> or 

will move the cursor one tabulator stop towards the left.

5.10 Move the cursor to the next tabulator stop - |-->, , |¶

Pressing the lower right arrow on the arrow pad:

Page 74¶

PED User's Guide¶

KEYS USED TO NAVIGATE¶

| ➜| or or |

will move the cursor one tabulator stop towards the right (see 4.6).

5.11 Move the cursor to the previous secondary tabulator stop - SHIFT + ←, FUNC V¶

Pressing the shift and the lower left arrow on the arrow pad:

SHIFT + | ⬅ | or FUNC V

will move the cursor one secondary tabulator stop towards the left.

5.12 Move the cursor to the next secondary tabulator stop - SHIFT + ➝, FUNC K¶

Pressing the shift and the lower right arrow on the arrow pad:

SHIFT + | ➡ | or FUNC K

will move the cursor one secondary tabulator stop towards the right.

5.13 Search for - SHIFT + F7, FUNC , G¶

The command is used when you want to find a word or an expression (a string) used in your buffer, to check or modify it. The HOME command G is identical in function to SHIFT + F7.

SHIFT + | F7 | or FUNC

When you press the SHIFT key and F7 you will get the following text in the screen HOME position:

GET-STRING:

and your answer can be either:

1) GET-STRING:↲

where is the expression you want to find

or

ND-60.121.4

Page 75¶

PED User's Guide¶

KEYS USED TO NAVIGATE¶

2) GET-STRING:↵¶

When you give ↵ in example 1, the system will be ready to search for throughout the whole buffer.

When the ↵ is pressed after in example 2, PED will ask for AREA: in the upper, right corner of the screen. This means that it is possible to tell PED to search for only within a given part of your buffer. Now indicate where this area can be found by typing in the first line and the last line of the area, in the following manner:

AREA: :

or

or

Example:¶

GET STRING: <ped>↵ AREA: 10:260,↵

or

GET STRING: <ped>↵ AREA: 10.5:260.20,↵

The search for starts in the current screen window, and the system indicates

SEARCHING FOR "string"

in the HOME position. If you want to continue to look for further occurrences of the same string, you use the F7 key explained below. If the whole region is being searched, PED will carry out the search until it reaches the end of the buffer. It will then jump to the first line of the first screen window, and continue with further prompts from you until it reaches the point where the search was initiated.

Each time is found, the system positions the cursor at the first character in and waits for you to decide whether you will edit it or simply go on.

The search can be continued in this manner until PED replies

"string" NOT FOUND

which means that PED has searched through the search area, and that it can not find any "string" between the last occurrence and the position you initiated the search. If you want to restart the search, you may press F7 once more.

ND-60.121.4

PED User's Guide¶

KEYS USED TO NAVIGATE¶

You may interrupt the search at any time by pressing the HOME key.

The SHIFT F7 (search for <string>) function will take into consideration the value of CASE SIGNIFICANCE in Menu no. 2. In other words, if the value of CASE SIGNIFICANCE is YES, SHIFT F7 will only find the exact replica of <string>.

Example:¶

GET-STRING: ped will not find PED.

If CASE SIGNIFICANCE is NO, the system will find both upper-case and lower-case versions of your string and will therefore pick up ped, PEO and Ped.

Note that SHIFT F7 will 'remember' the last string searched for, which enables you to restart the search for a string again much later. The absolute condition here is that you have not initiated a search for another string, or used the SUBSTITUTE command in the meantime.

5.14 Continue Searching - F7, FUNC \, \<G>¶

If you press the F7 key, the system will continue the search initiated with SHIFT F7 as explained above. F7 can be used either in HOME position or in the text.

F7

or FUNC \ or \<G>

F7 'remembers' the last <string> searched for, and will resume the search for this last <string> requested if you press it again after the search has terminated or has been interrupted with . If no search string is defined, the F7 key will act like the SHIFT + F7.

5.15 Scroll Display Window Up - SCROLL-UP, FUNC ↑¶

Pressing the topmost left double arrow:

PED User's Guide¶

KEYS USED TO NAVIGATE¶

will scroll the display window n lines up, enabling you to re-examine n lines of text already written, but no longer visible on your screen because it has scrolled out of the display. The value of n will be computed as the percentage given in Menu no. 1 (vertical step), of the height of the window. This percentage is default 93. This means that if you have a window of 10 lines, the scroll up key will move you 9 lines up. If you only have one window on the NOTIS-2200/9 terminal, you have 21 lines. This will give a scroll of 19 lines.

5.16 Scroll display window right - SHIFT + SCROLL-DOWN, FUNC ↦¶

Pressing the topmost right double arrow in shift position:

SHIFT + ⇥ or FUNC ↦

will scroll the display window n positions to the right, thus displaying text which lies beyond the right hand side of the window. The number n is computed from as a percentage of the window width. The percentage is given in horizontal step in Menu no. 1. Default value is 50, giving a horizontal scroll of half the window width.

5.17 Scroll display window left - SHIFT + SCROLL-UP, FUNC ↤¶

Pressing the topmost left double arrow in shift position:

SHIFT + ⇦ or FUNC ↤

will scroll the display window n character positions towards the left again, thus resetting the display window in the usual editing position. The value of n will be the percentage of the width of the window given in Menu no. 1 (horizontal step).

5.18 Scroll display window down - SCROLL-DOWN, FUNC ⇣¶

Pressing the topmost right double arrow:

will scroll the display window ‘n’ lines down. The value of ‘n’ will be computed as the percentage given in Menu no. 1 (vertical step), of the height of the window. This percentage is default 93. The command enables you to see existing text which is ‘n’ lines further on in your work area.

5.19 Move to previous area, menu etc. - <====, FUNC 8¶

Pressing the wide left arrow:

<==== or FUNC 8

will enable you to:

a) move to a previous parameter in a command with several parameter prompts.

b) move to previous menu.

c) move to previous HELP chapter when in HELP mode.

d) move to the end of previous word if no text is marked, and you are in the text area.

e) mark the previous line as FIELD if an area is marked.

KEYS USED TO NAVIGATE¶

5.21 Move the cursor to the beginning of this line - SHIFT + <====, <R><R>¶

Pressing the left wide arrow in shift position:

SHIFT * <==== or <R><R>

will move the cursor left, to the first character position on the current line. See also the <R> command.

5.22 Move the cursor to the end of this line - SHIFT + ====>, <F><F>¶

Pressing the right wide arrow in shift position:

SHIFT * ====> or <F><F>

will move the cursor to the character position after the last character you have input on the current line. See also the <F> command.

5.23 Display the first text window - F¶

Pressing the HOME command F will bring up on the screen the first screen window of edited text in the current region.

F

5.24 Display the last text window - L or $¶

Pressing the L will bring up on the screen the last 10 lines of edited text in your buffer, and approximately 10 blank lines, depending on the terminal you are working on.

L or $

When you now press the HOME key to move the cursor down into the text, the cursor will automatically be positioned one line below the last line of text.

ND-60.121.4

Page 81¶

5.25 Display the next text window - N¶

Pressing the N will bring the next screen window of edited text in the work area up on the screen.

N

The N command is different from the HOME command, in that the N will scroll the full window height, and will not be affected by the "vertical step" parameter in Menu no. 1. If a rapid sequence of N's are input, PED will count them, and will only display the final window.

Example:

You are working in the screen window containing lines 1342 - 1362. You go into HOME position, press N, and thus bring up on the screen the window containing lines 1363 - 1383.

5.26 Display the previous text window - P¶

Pressing the P will bring the previous screen window of edited text in the work area up on the screen. The comments on the N command also affects this command.

P

Example:

You are working in the screen window containing lines 1342 - 1362. You go into HOME position, press P, and thus bring up on the screen the window containing lines 1321 - 1341.

5.27 Advance the displayed text by 5 lines - plus¶

The + command causes the window to be advanced by 5 lines of text. This is useful if you want to check a block of text, a part of which is found at the top of the next screen window.

ND-60.121.4

+

5.28 Rewind the displayed text by 5 lines - minus¶

The - command causes the window to be rewound 5 lines. It thus has the opposite effect of the + command described above, and gives you the opportunity to review a few lines of text from the previous screen window, while keeping most of the text you are currently working on visible on the screen.

-

5.29 Move display to - M¶

The M command will move the text displayed on the screen window so as to make the line number indicated in appear as the first text line on the screen.

M

The command may be given relatively or absolutely. There are thus several ways in which the M command can be given:

1) MOVE TO POSITION:
where is the number of the line in the work area that you want to be displayed on the first line of the screen,

or

2) MOVE TO POSITION:(<+> or <-> )
where + or - (number of lines) will move the display the specified number of lines forwards or backwards in the work area.

3) MOVE TO POSITION:()
where will be the character position displayed in the upper left corner of the screen window.

4) MOVE TO POSITION:
where will be a named area in the buffer. If the area does not exist, it has to be created by putting double quotes around the name. If position in the region is not specified, you will enter the region where you left it earlier, and with a new region you will be placed at the beginning. You may also

5) MOVE TO POSITION:¶

where region is the region you move to and will be the character position displayed in the upper left corner of the screen window.

Example 1:¶

If is 300, lines 300 through 320 will be displayed.

Example 2:¶

If you are working on a screen window displaying lines 700 to 720 and you give as +15, your command will move you 15 lines forwards in the work area relative to the current window position. You will thus display the window starting with line 715.

Example 3:¶

You want to move to column 15 in line no. 750. You input <750.15>. Line no. 750 will be displayed as the first line of text in the screen window, and the character which occupies column 15 in line 750 will be displayed in the first character position in that line. In other words, the text will be scrolled 14 character positions towards the left.

Example 4:¶

If region is FILE-IO, the current region will change to FILE-IO, and the window will display that text, and the new region name, and the new lines and columns are indicated in line 2 of the screen.

Example 5:¶

If you specify FILE-IO.100.10, your new region is FILE-IO, and the lines displayed starts with line 100, and the leftmost column displayed is column 10.

5.30 Enter the work area at for editing - "¶

The " command enables you to move the cursor to the exact line and column in the text area where you want to edit text.

"

When you type " the system will prompt:

ENTER POSITION:

The parameter is or or , which can be marked with a 〈∨〉 (see 'functions without special function keys') and 'remembered' for as long as it remains the last item to have been marked in this manner. The specified position will be placed in the upper left corner of your current window.

+---------+ | Example:| +---------+

You have a column of figures starting on line 1500, column 50. You position the cursor on line 1500, column 50 and press 〈∨〉. You then move to another window to edit text, and when you want to return to your column of figures you simply press "in home position, and then 〈,〉. The system will now list out the marked with 〈∨〉, and another 〈,〉 will place the cursor at that position.

ENTER POSITION: 〈,〉1500.50〈,〉

You may, of course, also input the parameter manually, if you can remember it:

ENTER POSITION: 1500.50〈,〉

5.31 Move to another window - FUNC 1, FUNC 2, FUNC 3¶

When using the split screen facility, the way to move between the three windows is to use FUNC and the number of the window you are moving to.

6 KEYS USED TO MARK TEXT AREAS¶

As you will see in the top row of function keys on your TDV-2200/9 keyboard, there are two keys called MARK and FIELD. These keys are used to mark portions of text to be used for one of the purposes described in the chapter on 'Keys used to operate on marked text areas', i.e., text to be moved, copied or deleted.

The wide arrows

⇦⇦⇦⇦ ⇨⇨⇨⇨

or

FUNC B FUNC N

can be used to mark the previous/next occurrence of the same type as that already marked, e.g., if you mark a line, the left wide arrow will move you to the next line and mark that instead. The default value of area is field. When using the left wide arrow, the cursor position will be at the end of the selected area and when using the wide right arrow, the cursor position is at the beginning of the area.

If you regret a marking, press the CANCEL key (FUNC X) to cancel it. If you then regret the cancellation, you can make the marks reappear with SHIFT + CANCEL. (FUNC Q)

Marked text will appear in inverse video on your screen. Once text has been marked you have to carry out one of the operations mentioned above, before you can input more text in front of the marked area. If you try to enter more text before or in the marked area, before you have carried out an operation on the marked text you will receive a message in the top line of the screen:

PED: Press cancel key if you want to edit/input text

6.1 Mark top left/bottom right corner of a box area - MARK, FUNC ¶

When you wish to mark a box, e.g., a table or form, you may do so with:

SHIFT + MARK

or

MARK

or FUNC
or FUNC

ND-60.121.4

Page 89¶

PED User's Guide¶

KEYS USED TO MARK TEXT AREAS¶

The box has to be rectangular or square. You press MARK the first time in the upper left corner of the box, and a second time in the lower right corner of the box. The marked box now comes out in inverse video and is ready for one of the operations mentioned earlier.

If the box you wish to mark for further use is alone in the middle of your text, as is the

| MARK |

in this section, you may well mark it by pressing the MARK keys in the first character position of the first and of the last line in the block. You will then see that not only the block itself, but the whole length of the marked lines from the first to the last character position will be marked in inverse video. The block is then considered as whole lines and will, if moved, be reinserted in exactly the same character positions as those in which it was located in the original position.

The text will always, if such an operation is carried out with full lines, be inserted above the line on which the cursor was placed when you pressed the COPY key, and existing text will open up to make room for it.

If you want to move the block into other character positions, it is only the upper left and lower right corners that should be marked before you place the cursor in the new character position where you want the block to start when inserted.

A marked block can of course also be used in other operations than the MOVE function.

6.2 Mark this line - FIELD, FUNC F¶

| FIELD |

or FUNC F

If you press this key while the cursor is somewhere on the screen line, in any character position, the whole line from character position 1 to character position 255 (maximum line length) will be marked in inverse video and can be used in one of the operations mentioned.

7 KEYS USED TO OPERATE ON MARKED TEXT AREAS¶

When an area has been marked either with the MARK key or with the defined FIELD keys, you may use it in either one of the operations described in this chapter. Some function commands have equivalent HOME commands. The HOME commands are generally more flexible, and they can be simpler to use if you use non-NOTIS terminals. On NOTIS terminals, the function commands are faster to use.

7.1 Delete the marked area - DELETE, FUNC D, D¶

Once an area has been marked, you may delete it by pressing:

| DELETE | or FUNC D |

The marked area is then deleted, and the text contracted to fill the space where the area previously was.

An area can also be deleted by the home command D. PED will answer with

PED: Delete area:

All legal area parameters are legal inputs. If an area is marked, and you type ↓, PED will display the area, and wait for the user to type another ↓, or edit the displayed values.

7.2 Replace the marked area with spaces - SHIFT + DELETE, FUNC ¶

You may also choose not to have the text contract when an area has been deleted. In that case you press:

| SHIFT + DELETE | or FUNC |

The area is deleted as with the DELETE key, but the vacant space in the text area is filled with spaces and thus remains open.

7.3 Copy the marked area, insert it at cursor position - COPY, FUNC C¶

A marked area can also be copied into another part of your text document. This is done with:

ND-60.121.4

Page 95¶

PED User's Guide¶

KEYS USED TO OPERATE ON MARKED TEXT AREAS¶

| COPY | or FUNC C |

You mark the area of your choice, position the cursor in the text area at the point where you want the text inserted, and press COPY.

The text will open up to make room for the insertion. If you are copying whole lines, the text will be inserted above the line where the cursor is positioned. If you are inserting an area which does not consist of whole lines, the insertion takes place before the character position the cursor is on.

The text area you have moved of course also remains intact in its original position.

7.4 Replace cursor position area with the marked area - SHIFT + COPY, FUNC I¶

This command will overwrite the text at the cursor position with the text taken from the marked area. This is done with:

| SHIFT + | COPY | or FUNC I |

You mark the area of your choice, position the cursor in the text area at the point where you want the text replaced, and press SHIFT + COPY.

The text area you have moved also remains intact in its original position.

7.5 Move the marked area, insert it at cursor position - MOVE, FUNC M¶

Another possibility is to move a text area to a new location, at the same time deleting it where it was originally input. You then press:

| MOVE | or FUNC M |

and otherwise you apply exactly the same rules as in the COPY function above.

ND–60.121.4

Page 96¶

PED User's Guide¶

KEYS USED TO OPERATE ON MARKED TEXT AREAS¶

7.6 Replace cursor position area with marked area, spacefilling the marked area - SHIFT + MOVE, FUNC E¶

Another possibility is to move a text area to a new location, at the same time spacefilling it where it was originally input. You then press:

SHIFT + MOVE or FUNC E

and otherwise you apply exactly the same rules as in the SHIFT + COPY function above.

7.7 Insert area - I¶

The insert area command I is a home command equivalent to the function commands COPY and MOVE. The parameters are:

Insert area.

Destination.

Delete source.

If an area is marked, this is the default for the first parameter. If no area is marked by MARK or FIELD, the two last places (▼) was used is the default parameter.

The destination parameter's default value is the current cursor position.

The default answer to "Delete source" is N.

Example:

PED: Insert area: ↵ 190.22:197.34 ↵

Destination: ↵ 180.39 ↵

Delete source?: ↵

Now you had already marked an area 190.22:197.34 with the MARK function. You moved the cursor to the position 180.39 where you wanted to copy the area. The first ↵ as response to the parameters indicate that you want the default parameters displayed. You are satisfied with the defaults, and you want to copy rather than move the area. Legal inputs to the last question is Y, N, ↵, where ↵ means N. While you are editing parameters, HOME will interrupt the command.

ND-60.121.4

Page 97¶

7.8 Cancel the current area marking - CANCEL, FUNC X¶

If you have marked an area and then decide not to do anything with it after all, you may cancel the marks by pressing:

| CANCEL | or FUNC X |

The cancel command can also be used to recover the old version of a text region after a DELETE, COPY, or MOVE command on a marked area is executed. If there is no marked area when you press the CANCEL key, the command will undo the editing performed on the current line (whether this was replacing, adding or deleting text).

If there has been no editing on the current line, the command will cause the very last line deleted with the F1 key, or a marked area deleted with the DELETE key, to be restored and inserted above the current line.

If no lines have been deleted with F1, there is no marked area and no editing performed on the current line, the CANCEL key will cause a blank line to be inserted at cursor position. This is rare, however, since it is most probable that you have used the F1 key at some point in your text.

7.9 Re-mark the last marked area - SHIFT + CANCEL, FUNC Q¶

You may cancel a marked area, and then discover that you want to do something with it after all. You may then re-mark the same area, i.e., the same line and column numbers and area type, without having to go looking for it. Press:

| SHIFT + CANCEL | or FUNC Q |

and the area will be re-marked for a MOVE, COPY or DELETE operation. However, if you have for instance inserted a line before the marked area in the meantime, you will not get the same text remarked.

7.10 Convert the marked area to lower case characters - F6, FUNC I¶

If an area has been marked with one of the MARK functions described under 'Keys used to mark text areas', the marked area may be converted to lower case with

ND-60.121.4

Page 98¶

PED User's Guide¶

KEYS USED TO OPERATE ON MARKED TEXT AREAS¶

Key Function

F6 FUNC L

If there is no marked area, the function causes the remainder of the current line, i.e., all text between cursor position and the end of the line, to be converted to lower case.

7.11 Convert marked area to upper case characters - SHIFT + F6, FUNC U¶

If an area has been marked with one of the MARK functions described under 'Keys used to mark text areas', the marked area may be converted to upper case with

Key Combination Function

SHIFT + F6 FUNC U

If there is no marked area, the function causes the remainder of the line, i.e., all text between cursor position and the end of the line, to be converted to upper case.

7.12 Substitute with - S¶

This command allows you to automatically replace one string within the text with another.

Key

S

The substitutions may be carried out throughout your buffer, or only in a given AREA.

The search for the to be substituted will be carried out starting at the current text window, and proceed through the chosen search area. If no area is specified, the whole region is searched. When the search has come to the end of the search area, PED will continue at the beginning if current position is not at the beginning.

|<-- Search area Search path |<-- Current position

ND-60.121.4

Page 99¶

PED User's Guide¶

KEYS USED TO OPERATE ON MARKED TEXT AREAS¶

Pressing the character S will activate the SUBSTITUTE command. The format of the command is:

SUBSTITUTE: <old string> WITH: <new string> AREA:<from>:<to> MANUAL CHECK: <yes or no>

where:

<old string>: is the string to be replaced.

<new string>: is the replacement string.

AREA:<from>:<to>: is the part of the text where you want the substitutions to be carried out.

If you have marked the AREA with <V>, you just input ↵.

<yes> / <no>: is input Y or N.

↵ will be taken as Y.

The AREA: parameter is optional and if the <new string> is terminated with ↵, AREA will not be asked for.

If the answer to manual check is YES, and if <old string> is found, the cursor will be placed under the first character in the string, and PED will wait for a decision as to whether or not the <old string> should be replaced with the <new string>.

The following decisions are possible:

S or Y: Substitute and search for next <old string>.

\: Terminate substitute command.

The cursor is placed in the HOME position again, and the number of substitutions carried out is indicated: 'n' SUBSTITUTIONS.

Anything else: Continue to next <old string> (i.e., do not substitute).

If the answer to manual check is NO, PED will carry out all the substitutions automatically throughout the text and indicate: 'n' substitutions in the HOME position at the end of the operation.

The new string will automatically be set as the string to be searched for, if a <G> or F7 command is given afterwards to initiate a continued search operation.

COMMANDS USED TO EDIT TEXT¶

8 COMMANDS USED TO EDIT TEXT¶

This chapter is devoted to commands used in the edit buffer to edit text. Some commands are function key commands, while others are control key commands. When a command is written <X>, this means that you have to hold the ctrl key down when you push the character inside the < >. Upper and lower case is equal when used with the ctrl key. This means that <c> and <C> has the same meaning. Some places the command FUNC is found in the text. This is used for key input of the ASCII value 37B. On some terminals this is input as <UNDERLINE> or <SHIFT UNDERLINE>.

8.1 Function key commands¶

8.1.1 Delete this line - the F1 key, <D><D>, FUNC <D>¶

Pressing the F1 key:

F1

or <D> <D> or FUNC <D>

will cause the line on which the cursor is positioned to be deleted.

If you find that you did in fact not want to delete the line, you may restore it with the CANCEL key.

CANCEL

or FUNC X

The last line or area deleted will be remembered and may be restored with the CANCEL key. You may therefore insert a line at one or several different locations in the text, by deleting it with the F1 key and restoring it with the CANCEL key.

You may similarly insert a block of whole lines at several different locations in the text by first marking the block of lines, deleting them with the DELETE key and then restoring them at the required locations with the CANCEL key.

NO-60.121.4

Page 103¶

PED User's Guide¶

COMMANDS USED TO EDIT TEXT¶

When a line or block is deleted in this manner, the line below it is moved up and the gap in the text filled.

When the line or block is restored with the CANCEL key, the text is opened up again to give room for it above the line on which the cursor is positioned. If you only want to restore the last deleted line, the command <W> will insert it before the current cursor line. This command can be repeated several times, and works this way as a quick copy of one line at a time.

F1 only responds while the cursor is in the text area.

If you only want to delete part of your line, see the command <D>.

8.1.2 Insert a new line here - the F2 key, , FUNC ¶

When you press the F2 key:

| F2 | or | or FUNC |

A blank line is inserted above the line on which the cursor is positioned. This enables you to insert one or several new program lines at a given point in your file. You may press this key as many times as you wish, thus opening up the number of lines you need.

F2 responds only when the cursor is in the text area.

8.1.3 Delete character - a, DEL, ¶

Pressing the a with the slash through it:

| a | or DEL | or |

Will cause the character on which the cursor is positioned to be deleted. The line will be contracted and the position where the character was deleted will be filled.

Example:¶

You write 'wrrite' instead of 'write'. You position the cursor on one of the 'r's, press the delete key, the extra 'r' is deleted and the word is contracted to 'write'.

If you press á while the cursor is positioned after the last character on the line, it is the character preceding the cursor position which will be deleted.

Example:¶

You have a line of text which ends with a full stop. The cursor is positioned immediately after the full stop. If you now press á, the full stop will be deleted.

If you use the á key while the cursor is placed on an empty line, or on the right hand side of the text, PED will then give a bell, and position the cursor immediately behind the last character on the line, or in position 1, if the line is empty.

8.1.3.1 Alternative delete mode¶

The function of the delete key is affected by a flag which is set by the command FUNC DEL (FUNC á). This is called alternative delete mode. If the indicator ⊕d is set on the status line when this mode is on.

The change in function of á does not change the function of ⟨A⟩.

The alternative delete mode is active when the last you did was typing text, and will then delete the last typed character, and move the cursor one step to the left. If you position the cursor with one of the arrows, or do anything but type text, the alternative delete mode will be passive until you type a character again.

If expand mode is off, text to the right on the same line will not be moved.

If expand mode is on, the text to the right is moved one character position to the left, following the cursor.

ND-60.121.4

Page 105¶

Example:¶

Alternative delete mode is on, and expand mode is on.

Before á typed (last key typed is the e) the line looks like:

procedure readfromefile (var inchar : char);

After the á is typed the line is:

procedure readfrom¡ile (var inchar : char);

If the flag is not set, or if you input <A> instead, the f is deleted. This will also happen if you position the cursor prior to using the á key. This is how it will look like:

procedure readfrome¡le (var inchar : char);

If expand mode is off, and you type the á key, the line will look like:

procedure readfrom_file (var inchar : char);

As you see, the text to the right is not moved. This is particularly valuable for editing programs if you do not want to change your comments on the right side of the screen. This feature will also make editing of tables easier.

8.1.4 Split the line at cursor position - F5, FUNC Y¶

By pressing

| F5 | or FUNC Y |

you cause the line on which you are working to be split at cursor position, and the part of the line which is behind cursor position to be moved down to the next line.

8.1.5 Link this line to the preceding line - SHIFT * F5, FUNC Z¶

By pressing the same key in shift position

ND-60.121.4

Page 106¶

PED User’s Guide¶

COMMANDS USED TO EDIT TEXT¶

SHIFT + | F5 | or FUNC Z

the line the cursor is on will be appended to the line above the cursor.

8.1.6 Move the cursor to the beginning of this line - SHIFT + ⇐ , FUNC , ¶

Pressing

SHIFT + | ⇐ | or or FUNC

moves the cursor left, to the first character position on the current line.

8.1.7 Move the cursor to the end of this line - SHIFT + ⇒ , FUNC , ¶

Pressing the right wide arrow in shift position or :

SHIFT + | ⇒ | or or FUNC

moves the cursor to the character position after the last character on the current line.

8.2 Control key commands¶

8.2.1 Accept control character - ¶

The command allows any edit or control character to be accepted as a normal character.

Pressing followed by a control character causes PED to insert the control character in the text at the current cursor position. Control characters will be written out on the screen as '&'. Their values can be verified with while the cursor is positioned at the &, or with the HOME command V. The users are warned that PED will expand all (ASCII 118) on input from file unless a TAB- command is placed on the first line of the file.

ND-60.121.4

Page 107¶

PED User's Guide¶

COMMANDS USED TO EDIT TEXT¶

This function should not be used in text files, since the control keys may be taken as commands to either NOTIS-TF or a printer.

8.2.2 Undo editing on this line¶

The <W> command works like CANCEL, but limited to one line at a time. The functions are:

Restore current line to original contents when the line is changed.

Restore last line deleted by F1 or <D><D> when current line is not changed.

Note that <W> does not restore lines deleted as FIELDS.

<W> may also be used as a HOME command, to repeat the last command given in the HOME position. This function is attractive when you have typed the file name wrong in a read or write command. The <W> will recall the file name ready for you to correct it.

8.2.3 Copy one character from previous to current line - ¶

The <C> command is used to copy one character from the previous non-empty line into the current line. Position the cursor on the current line, directly under the character to be copied. Press <C>. The character will be copied into the current line at the cursor position, and the cursor moved one position to the right.

8.2.4 Copy one character from next to current line - ¶

The <N> command is used to copy one character from the next into the current line. The procedure is the same as for <C> above, except that the cursor must be positioned directly above the character to be copied.

8.2.5 Move cursor forwards to specified character on the line - char¶

The <F>char command moves the cursor forwards to the first occurrence of char on the current line.

Some special characters:

Command Description

<F> The cursor is moved to the position after the last significant character on the current line.

NO-60.121.4

Page 108¶

PED User's Guide¶

COMMANDS USED TO EDIT TEXT¶

the cursor is moved forwards to the right margin.

When editing in the command line in HOME position, <F><F> moves the cursor to the end of the command parameter.

8.2.6 Move cursor backwards to specified character on the line - <R>char¶

The <R>char command moves the cursor backwards to the first occurrence of 'char' on the current line.

Some special characters:

Character Description

<R> the cursor is moved to the first character position on the current line.

- the cursor is moved backwards to the left margin.

When editing in the command line in HOME position, <R><R> moves the cursor to the beginning of the command parameter.

8.2.7 Copy characters from previous line to current line - char¶

The char command enables you to copy into the current line all characters from the previous non-empty line that are to the right of cursor position, up to and including 'char'.

Some special characters:

Character Description

 all the characters between cursor position and the end of the line are copied into the current line.

- all the characters between cursor position and the end of the line are copied into the current line, and the cursor moved to the beginning of the next line.

 or <T> all the characters up to the next tabulator position are copied into the current line.

- or TAB all the characters up to the next tabulator position are copied into the current line.

SHIFT * (-) or FUNC K all the characters up to the next secondary tabulator position are copied into the current line.

The line may be restored by CANCEL or <W>.

ND-60.121.4

Page 109¶

8.2.8 Copy characters from next line to current line - FUNC
char¶

The FUNC
char command enables you to copy characters from the next line into the current line. It is otherwise carried out in exactly the same manner as the
char command above.

8.2.9 Delete characters up to and including char - char¶

The char command enables you to delete parts of a line of text, or the whole current line.

If char is:

Command Description

The whole line is deleted and the text below moved one line up to fill the gap.

↓ The line is deleted from cursor position to the end of the line.

The line is deleted from the beginning of the line up to but not including cursor position.

or or TAB or → The line is deleted from cursor position to the next tabulator position.

or or BTAB or ← The line is deleted from cursor position to the previous tabulator position.

FUNC K or SHIFT → Delete characters from cursor position to next secondary tabulator stop.

FUNC V or SHIFT ← Delete characters from the previous secondary tabulator stop to cursor position.

ordinary character Delete up to and including first character equal to the character.

A line deleted with can be restored with CANCEL or . It is then restored on the line above cursor position.

Have you deleted inside a line, it can be restored if you have not moved out side the line.

LINE MODE EDIT¶

ND-60.121.4

Page 112¶

9 LINE MODE EDIT¶

Although this editor is best used on a terminal with cursor addressing capabilities, it can also be used on "teletype" style terminals, and on teletypes. The editor is also set in this mode if the VTM-table contains some serious error. VTM will continue to ask for a terminal type until the type specified is found on the file (SYSTEM)DDPTABLES-C:x:VTM. (The letter x may change.) The line mode may be used on all alphanumeric teletype-compatible terminals. To enter line mode from page mode, use the command #.

The editor is in many ways similar to the QED standard ND editor (see the QED Users Manual NO-60.031), but is more advanced than this. Most of the HOME commands from page mode (normal running mode) can be used. They are not immediate response commands however, but are of a "SINTRAN MATCH" type. Some commands are particular to this mode, and these are explained in more detail below.

9.1 Shadow line¶

The shadow line is used for supporting safe editing and fast input of similar lines. The content is different in the two modes:

Input mode The previous line is copied into the shadow line.

Edit mode The old content of the edited line is copied into the shadow line before edit is performed.

When the INSERT-LINE command is given, the initial value is the following line, not the previous. Some of the commands use the shadow line. If the terminal in use is a VDU, the shadow line will be displayed in edit mode.

9.2 The commands¶

The commands are listed with the QED equivalent inside { } parenthesis, if a QED command exists. The equivalent page mode command is displayed inside [ ] brackets. Parameters are inside < > brackets. If they are also inside ( ) brackets, they are optional parameters.

PAGE-MODE:.

The command is used to return to page mode edit. If the terminal type specified does not permit page mode editing, the message:

Terminal is not defined with cursor control

will be given, and the editor will continue in line mode. If you only type page-mode, the editor will test if your terminal type allows for cursor control, and if so, return you to page mode. If you are aborted, and use the &CONTINUE command, PED will restart in page mode if possible. You may then use the # command to enter line mode.

Page 113¶

LIST-AREA <area>¶

{L} This command will display all lines as defined in the area parameter. If no area is specified, the current line will be displayed.

NEXT-LINES <number of lines>¶

{N} Displays the next "number of lines". Current line is updated to the last displayed. Default number of lines is 1.

PREVIOUS-LINES <number of lines>¶

{P} Displays the previous "number of lines" in inverted order. Current line is the last displayed. If no parameter is given, the previous line is displayed.

Example:¶

PED: list-area 34> end; PED: previous-lines 5 33> end; 32> count := count + 1; 31> end; 30> k := k * prim; 31> flags [k] := false; PED: list-area 31> flags [k] := false;

LINE-NUMBER-DISPLAY NO/LEFT/RIGHT¶

The value given determines the line numbering displayed on the terminal.

Mode Description

NO No line numbering is displayed.

LEFT Line numbering is displayed on the left side of the screen. The numbers are succeeded by a '>' and a space. The numbers are not a part of the text, and are only displayed as a help for the user. This numbering mode is default.

RIGHT Line numbering is displayed on the right side of the screen.

EDIT <line>¶

{E} is the command used to start editing a line. If <line> is omitted, the current line is edited. <L> at the beginning of the line will delete the line.

Page 114¶

PED User's Guide¶

LINE MODE EDIT¶

APPEND-NEW-LINES (behind line)¶

[A] PED is set in input mode, and all text input will be put after the specified line until a <L> is input. If the line parameter is omitted, current line is taken.

INSERT-NEW-LINES (before line)¶

[I] This works as APPEND-NEW-LINES, with the difference that the new lines will be put before the specified line.

DELETE (delete area)¶

[D] Default area is current line. See also the page command DELETE [D] on page 83.

INSERT-AREA (source area) (destination) (delete source?)¶

[I] See the page command INSERT [I] on page 85.

LINE MODE EDIT¶

EDIT CHARACTERS¶

(also in QED, but some differences should be noted)
PED will echo some of the control keys on hardcopy terminals (e.g., terminal types 2 and 11).

Key Description

\<A>/DEL Backspace one character [echo `]

\ Skip one character in old line (types Z)

\<C> Copy one character from old line

\<D> Copy rest of old line and terminate edit

\<E> Insert string from terminal (echo < to start and > to finish)

\<F> Copy rest of old line (without typing) and terminate edit

\<G> As command: continue search (no function in edit mode)

\<H> Copy rest of old line without terminating edit

\ Insert spaces to next tabulation stop in new line

\<J> Terminate edit. If parameter input, ask for next (as in page mode)

\<K> Restart the edit from the beginning (echo _ )

\<L> Terminate edit and input mode in any event, except after

\<M> Terminate edit (CR)(␍)

\<N> Copy next "word"

\<O>x Copy old line up to, but not including, character x

\x Skip characters in old line up to, but not including, character x (Z is echoed for each character skipped)

\<Q> Restart the edit from the beginning (types _ )

\<R> Delete next word

\<S> Skip one character in old line (types Z)

\<T> Type the rest of the old line and the new line aligned, then await more edit characters

\ Copy up to next tabulation stop

\<V>x Allows any edit character or control character to be accepted as normal characters (t)

\<W> Backspace one "word" (types backslash)

\<X>x Skip characters in old line up to and including the character x (Z is typed for each character skipped)

\<Y> Append rest of old line to new line and edit the result

\<Z>x Copy old line up to and including character x

\<J> Abort input/command

(**) When listing lines on the terminal, QED will mark control characters in the line by inputting a \ in front of each of them.

If line mode is used on a visual display terminal (a VDU), some visual screen editing is performed. Eg., when a character is erased with \<A> or DEL, this is visible and no \ is typed.

PED User's Guide¶

PED AND SYSTEM ERROR MESSAGES¶

ERROR TYPES¶

There are two different kinds of error messages, those from the file system and those from the editor (PED).

1) System messages¶

These error messages are described in the SINTRAN III Reference Manual ND-60.128.

2) Program Editor messages¶

These indications and/or error messages are given in the screen home position in connection with the commands you give.

We are listing the most usual messages, and would advise you to contact the System Supervisor if you are in doubt.

Error Message Description

Unknown command

The message is given if an unrecognized HOME command is input.

Line indicated is greater than the last line number

The message is given if the first line number indicated in an AREA: parameter is greater than the last line in the region.

Scratch file error - do you want to continue

The message is generally given because there is no more space under user SCRATCH.

This function cannot be used (now)

The message is given if you try to obtain a function which is authorized, but impossible; e.g., giving a GET STRING command before fetching text into the work area.

"" not found

The message is given both when a given as parameter to a search initiated with the Get String command cannot be found in the file, and when the search has come to an end and all occurrences of have been found in the search area. The message also occurs when attempting to move (M) to a non-existing region.

ND-60.121.4

Page 121¶

PED User's Guide¶

PEO AND SYSTEM ERROR MESSAGES¶

Search aborted at line number "n"¶

The message occurs if a search initiated with SHIFT F7 or F7 is interrupted with the HOME key before the whole search area has been searched.

The text is modified! Do you want to store it (Y/N)¶

The message is given if you try to exit from PED or activate PERFORM or NOTIS-TF, without storing your text in a file-name. The question has to be answered before you can continue.

No area selected for this function¶

The message is given if you forget to define an area before you try to carry out one of the functions for which an area is needed.

Press cancel key if you want to edit/input text¶

The message is given if, after having marked an area for an operation, you try to enter more text or perform other editing in front of the marked area before the operation has been carried out.

Fatal editor error in routine "n", please report to ND¶

The message must immediately be reported to your System Supervisor, for further action. Please write down what happened before the error message was given and the name of the routine.

Library error number "n", please report to ND¶

The message must immediately be reported to your System Supervisor, for further action. Please write down the function which caused the error, the current run mode (page-mode, line-mode) and the current terminal type.

String is too long.¶

The message is given if the string length exceeds 255 characters (current maximum line length) due to input in line mode or to a substitution where the new string is longer than the old ones. The line input is lost in line mode, while in a substitution the replacements will be carried out up to the one that causes the error and leads to abortion of the operation.

ND-60.121.4

Page 122¶

PED User's Guide¶

PED AND SYSTEM ERROR MESSAGES¶

Ambiguous command.¶

Given in line mode only, if an ambiguous command is input.

The function is not implemented in this version.¶

The message may be given if a function is omitted from a version of PED.

Serious error, back storage overflow.¶

The message will occur when the current version of PED is run, if the current use of the back storage (the scratch file) exceeds 6100 SINTRAN pages (approx. 40000 lines filled with 80 characters each).

Cannot open file¶

The message is likely to occur if another user has accessed the file while the current user was in SINTRAN, eg., outside the editor.

Terminal not defined with cursor control.¶

The message is given if the page mode command is input in line mode on a hard copy terminal or on a VDU defined without cursor positioning possibilities. Contact the System Supervisor, who will check the accuracy of the D08xxx file installation.

Missing string/expression termination.¶

The message is given if one or more right parentheses are missing in a numeric expression, or if an end quote is missing in a string expression or when a search string is specified in line mode.

No help information available.¶

The file PED-ENG-x:HELP is missing or cannot be opened. Contact the System Supervisor, who will check if public access is set to R.

Invalid expression.¶

The message is given if there is an error in a numeric expression.

Attempt to create too many regions¶

PED can handle about 40 regions at a time. You have to delete a region in order to make room for the new one.

NO-60.121.4

PED User's Guide¶

Error Handling¶

In any interactive system, it is inevitable that errors will occur. This chapter describes PED newline some general areas in PED where error situations might occur, and how they are handled.

Types of Error Messages¶

The types of error messages within PED fall into three categories:

Informational

Warning

Error

Informational¶

Informational messages are used to provide feedback to the user for operational status or success. They do not require any action by the user.

Warning¶

Warning messages inform the user of potential problems that might require corrective action to avoid errors.

Error¶

Error messages indicate that an operation cannot be carried out. They require user intervention to correct the issue.

Common Error Messages¶

Error Code Description Action Required

ERR01 File not found Verify the file path and retry.

ERR02 Invalid command syntax Check the syntax and try again.

ERR03 Insufficient permissions Check access rights.

ERR04 Operation failed Try the operation again later.

This guide provides a brief overview of the different types of errors and how to handle them effectively to ensure a smooth experience with PED. Please refer to the detailed sections for comprehensive information on each error type.

PED User's Guide¶

The Menus¶

Two menus can be called up on the screen, one by one, by pressing 1 or 2 on your keyboard while the cursor is in the HOME position. You may go back and forth between the two menus with the double arrows.

<=== and ===>

or

FUNC B and FUNC N

Move the cursor back into HOME position when you want to return to your text file.

The menus contain operating instructions to the program editor. You are free to modify these values to suit your particular purposes, and may do so from your terminal while you are logged in under your personal user name. Your modifications will not interfere with other users’ menus. The options Y/N stand for YES or NO.

The two menus are listed below, with a short explanation.

Notation	Description
`<x>`	When occurring in the text it refers to a command performed by holding the CTRL key down while typing the key inside the angle brackets.
`&x`	This is another way of writing a non-writable character. It is not much used in the manual, but is the way PED writes control characters. If PED cannot print a character, a & sign is put instead. Use the `<v>` command to get the value of character.
`yB`	If y is a number, the B (or b) denotes that this is an octal number (i.e., base 8). This is standard in all ND documentation.
`FUNC`	On NOTIS terminals this is a function lead-in key placed on top of the numeric key pad. To perform this command on a non-NOTIS terminal, you have to input CTRL UNDERLINE (`< _ >`). (On some terminals underline is a shift character and the command is then CTRL SHIFT UNDERLINE). The ascii value is 378.
`⏎`	This sign is the marking of the carriage return key on a NOTIS terminal. (ascii 15B) On other terminals this may be marked as "RETURN" or "CR".
`⌂`	This is the sign on the HOME key on the NOTIS terminal. This may be marked "HOME" on other terminals.
`HOME position`	Topmost left corner of the screen. It is marked with PED:.

Line:	The numbers displayed are the line numbers within the first and the last line on the screen window.
Column:	The numbers displayed are the column numbers of the leftmost and rightmost columns of your screen window. This is normally 80 character positions, and if the first number is different from 1, you are not looking at the leftmost part of your buffer.
Region:	The region is the name of your current region. Default is MAIN. The commands for marking areas, or working with marked areas take current region as default region.
Position:	Indicates where in the buffer you are, relative to the first and last line. The file is divided into 10 equally-sized parts, and the cross indicates where you are now. Initially, when you start to write a new file, your position is "last" and the indicator is thus placed in the rightmost position.

Parameter	Description
Region	Region is an alphanumeric name of a region. A hyphen is accepted inside a name. The region must be known to PED. If you want to create a new region, use double quotes around the name. The region `MAIN` will always exist. If region is omitted, current region is assumed. Region names can be abbreviated. Regions are described on page 15.
First line	The first line to be affected by a command. This parameter can be given as an expression, as all the numeric parameters.
Second line	The last line to be affected by a command. If this one is omitted, and the first line is specified, the value given as first line will be filled in for the last line as well.
First column	The left margin of the text to be affected by a command. The default value of this parameter is column 1 for all commands.

Parameter	Default
region	Your current region as indicated in line two on the screen.

Operator	Description
xor	Computes the bitwise xor operation between the preceding and succeeding expression.
or	Computes the logical or between the expressions.
and	Computes the logical and between the expressions.
shift	Computes a bitwise shift operation on the preceding expression a number of times given by the succeeding expression. Positive number of times gives left shift, negative values give right shift.
abs	Computes the absolute value of the succeeding expression.
**	The first expression is raised to the power of the second expression.
mod	Computes the modulus of the two expressions.
@	Commercial 'at' is a variable containing the last computed result. It can be used in expressions, and is useful if your expression is too long, or too complicated to write on a line.

Symbol	Description
$	A missing CRLF on input is marked by a 'S' in the first character position of the broken line. This will occur if the input line is longer than 255 characters.
+	A missing LF is marked with a '.' in the first character position. This means that on output to a printer, the next line will be written upon this line.
