SINTRAN III Monitor Calls¶

ND-60.228.2 EN

1 MONITOR CALLS¶

SINTRAN III is the operating system on all ND computers. It provides various services such as reading the current time or writing to files. Programs request such services through monitor calls. A monitor call looks like a routine call.

Terminal	Program	Monitor calls	SINTRAN III ND-500-Monitor

SINTRAN III provides monitor calls to programs running on the ND-100 computer or the ND-100 processor of an ND-500 computer. ND-500 MONITOR is a SINTRAN III subsystem on ND-500 computers. It provides monitor calls to programs running on the ND-500 processor. Almost every monitor call exists on both ND-100 and ND-500.

Some monitor calls are only available to user RT or user SYSTEM. Programs not started by these users will be rejected. Other monitor calls may be used only in RT programs or only in background programs.

You should use monitor calls when a programming language does not provide a particular function.

Page 10¶

1.1 How to Use This Manual¶

Chapter 3 contains a detailed description of all monitor calls. They are sorted alphabetically. Each monitor call is described by two standard pages. The first of these pages is explained below:

MONITOR CALL NUMBER IN OCTAL	MONITOR CALL LONG NAME	MONITOR CALL SHORT NAME
758	GETSTARTBYTE

Gets the number of the next byte to access in a file. The bytes in a file are numbered from 0.

The file must be opened for sequential access.
You cannot use this monitor call for peripheral files.

See also SetStartByte and SetStartBlock.

INPUT PARAMETER
- PARAMETERS
- File number. See Openfile.

OUTPUT PARAMETER
- The number of the next byte to access.
- Standard Error Code. See appendix A.

ERROR CODE		EXAMPLES IN HIGH-LEVEL LANGUAGES
PASCAL
	fileNumber: INTEGER2;
	BytePointer: LONGINT;

	GetStartByte(fileNumber, BytePointer);
	If ErrCode <> 0 THEN ...

COBOL
	01 fileNumber COMP.
	01 BytePointer COMP PIC S9(10).
	01 ErrCode COMP.

	MONITOR-CALL "GetStartByte" USING FileNumber, BytePointer
	CALL "CbError" USING ErrCode.
	IF ErrCode NOT = 0 GO ...

FORTRAN
	INTEGER FileNumber
	INTEGER*4 BytePointer

SINTRAN III Monitor Calls¶

Monitor Calls¶

The following sections in this chapter show examples of how to compile and load programs. One example is provided for PASCAL, COBOL, FORTRAN, PLANC, MAC, and ASSEMBLY-500.

In Chapter 2, monitor calls are grouped according to functions. Use it if you do not know the monitor call which provides a particular function. Lists sorted by monitor call numbers and short names are also provided.

The last appendix contains a glossary.

SINTRAN III Monitor Calls¶

Monitor calls¶

1.2 Monitor Calls in PASCAL¶

The example below shows how to use monitor calls in a PASCAL program. The program checks the CPU number. Then it reads a name from a terminal and appends it to a file. The file is created if it does not exist.

PROGRAM StoreName (INPUT, OUTPUT);
VAR FileNo, Terminal, OutStat, I: INTEGER;
    InText: PACKED ARRAY [0..39] OF CHAR; (* String parameter. *)
    Buffer: BitMap;                       (* System defined type for monitor calls. *)
BEGIN
    Terminal := 1;                        (* Logical device number of the terminal. *)
    GetSystemInfo(0, Buffer);
    IF Buffer[0] <> 678 THEN ExitFromProgram;  (* Test CPU number. *)
    OutString(1, 'NAME: ', 6, OutStat);   (* Output prompt on terminal. *)
    FOR I := 0 TO 39 DO InText[I] := ' '; (* Spacefill InText. *)
    InString(Terminal, InText, 40, 141, OutStat); (* Terminal input. *)
    OpenFile(FileNo, 5, 'NAME-STORAGE', 'DATA'); (* Append access. *)
    IF ErrCode = 46 THEN                 (* ErrCode 46 means no such file. *)
    BEGIN
        CreateFile('NAME-STORAGE:DATA', 0,0);
        OpenFile(FileNo, 5, 'NAME-STORAGE', 'DATA');
    END
    ELSE IF ErrCode <> 0 THEN ErrorMessage(ErrCode);
    FOR I := 0 TO 39 DO OutByte(FileNo, Ord(InText[I]));  (* Store. *)
    OutByte(FileNo, 13);                 (* Out carriage return *)
    OutByte(FileNo, 10);                 (* Out line feed *)
    CloseFile(FileNo);                   (* Close file *)
    ExitFromProgram;                     (* Redundant statement. *)
END.

You should note the following with monitor calls in PASCAL:

The function ErrCode returns the standard error code. You need not declare this function.
The monitor calls sometimes use the types LONGINT, INTEGER2, BYTE, BYTE2 and BITMAP. BYTE2 is integers from 0 to 65535. BITMAP is defined as ARRAY [0..15] OF BYTE2. You need not define these types.
Buffer parameters as in GetSystemInfo may be declared as records. This simplifies access and improves the readability.
Some monitor call names are redefined in PASCAL to make the first 7 characters significant. This is commented in the examples.

Note
This usage of monitor calls is available from version A of the CAT-PASCAL compilers for ND-100 and ND-500. Do not use the old PASCAL-100 and PASCAL-500 compilers.

    MONITOR-CALL 'CreateFile' USING FileName I4 I4.
    MONITOR-CALL 'OpenFile' USING FileNo 5 FileName "DATA'".
    GO 200.

You should note the following with monitor calls in COBOL:

The routine CBERROR returns the standard error code. The variable ErrCode must be declared.
All strings input to monitor calls must be terminated with an apostrophe, eg., "DATA'".
All strings output from monitor calls should be declared with length 100, eg., 01 InText PIC X(100).
Parameters declared as PIC 9(10) cannot be given as constants.
You may use monitor call numbers and short names, eg., MONITOR-CALL 'ERMSG' USING ErrCode or MONITOR-CALL 64B USING ErrCode.

| This usage of monitor calls is available from version H of the COBOL-100 and COBOL-500 compilers. |

1.4 Monitor Calls in FORTRAN¶

The example below shows how to use monitor calls in a FORTRAN program. The program reads a name from a terminal and appends it to a file. The file is created if it does not exist.

PROGRAM StoreName
INTEGER FileNumber, NoOfBytes, Terminal, TextLength, I
INTEGER*4 Zero                % General purpose parameter.
CHARACTER InText*40;          % String to store terminal input.
Terminal = 1; TextLength = 0; Zero = 0
Monitor_Call('OutUpTo8Bytes',Terminal,'NAME: ') % To terminal.
DO FOR I = 1,40,8;            % Read 8 and 8 bytes from the terminal.
   Monitor_Call('InUpTo8Bytes',Terminal,InText(I:I+8),NoOfBytes)
   TextLength = TextLength + NoOfBytes; % Count number of bytes.
   IF (NoOfBytes.NE.8) GO TO 100; % Continue while more input.
END DO
100 IF (TextLength.EQ.0) THEN Monitor_Call('ExitFromProgram') ENDIF
C   Open the mass storage file for append access, i.e., type 5.
Monitor_Call('Openfile',FileNumber,5,'NAME-STORAGE','DATA')
IF (ErrCode.EQ.46) THEN;      % ErrCode 46 means no such file.
   Monitor_Call('Createfile', 'NAME-STORAGE:DATE',Zero,Zero)
   Monitor_Call('Openfile',FileNumber,5,'NAME-STORAGE','DATA')
ELSE IF (ErrCode.NE.0) THEN;  % Output error message.
   Monitor_Call('ErrorMessage',ErrCode)
ENDIF
DO FOR I = 1,40,8;            % Write 40 bytes to the file.
   Monitor_Call('OutUpTo8Bytes',Terminal,InText(I:I+8))
END DO
Monitor_Call('OutByte',13);   % Out carriage return.
Monitor_Call('OutByte',12);   % Out line feed.
Monitor_Call('Closefile',FileNumber); % Close file.
END

With monitor calls in FORTRAN you should note the following:

Error codes are automatically stored in the variable ErrCode. This integer variable ErrCode can be read as any other variable. It should not be declared. Use the compiler command STANDARD-CHECK OFF before compilation.
Parameters declared as INTEGER*4 cannot be given as constants.
You may use the monitor call numbers or the short names, eg., Monitor_Call('ERMSG',ErrCode) or Monitor_Call(648,ErrCode).

This usage of monitor calls is available from FORTRAN-100 version E and FORTRAN-500 version I.

      Char := InText(TextLength); TextLength + 1 := TextLength
    ENDWHILE
  ENDFOR
  IF TextLength = 0 THEN Monitor_Call('ExitFromProgram') ENDIF % Open the mass storage file for append access, i.e., type 5.
  Monitor_Call('OpenFile', FileNumber, 5, 'NAME-STORAGE:', 'DATA')

SINTRAN III Monitor Calls¶

Monitor calls¶

You should note the following with monitor calls in PLANC:

Error codes different from 0 cause ERRETURN from monitor calls. That is, the current ON - ENDON statement is executed.
Error codes are automatically stored in the variable ErrCode. This integer variable ErrCode can be read as any other variable. It should not be declared.
Parameters of type INTEGER4 cannot be given as constants.
You may use monitor call numbers or short names, e.g., Monitor_Call('ERMGS', ErrCode) or Monitor_Call(164B, ErrCode).
Monitor calls requiring large amounts of data may use records instead of strings, as in many of the examples in Chapter 3.

For example:

TYPE RTDescription = RECORD
    INTEGER2 : ...
    ...
ENDRECORD
RTDescription : AProgram
Monitor_call('GetRTDescr', RTProgram, AProgram, NoOfConnDev)

Compile, load, and execute the program on an ND-100 computer as shown below. You need the library file MON-CALL-1BANK:BRF. It provides the monitor call routines. Your input is underlined.

A large program may need more than 128 Kbyte memory space. In that case, you should give the command SEPARATE-DATA ON before COMPILE. Then load the program with the libraries MON-CALL-2BANK:BRF and PLANC-2BANK:BRF instead of the ones shown. See the BRF-LINKER USER MANUAL (ND-860196) for more details.

You compile, load, and execute a program on the ND-500 processor as shown below. The library MON-CALL-LIB:NRF provides the monitor call routines. See the manual's PASCAL User Guide (ND-860124), and ND-500 Loader/Monitor (ND-860136) for more details.

SINTRAN III Monitor Calls¶

Monitor Calls¶

You should note the following with monitor calls in ASSEMBLY-500:

Error codes different from 0 set the K register. The error code is returned in the W1 register.
The second parameter to CALLG is the number of following parameters.
Only the monitor call name declared as a constant or the monitor call number are allowed in monitor calls.
Monitor calls only available on the ND-100 cannot be executed.
All string parameters must be terminated with an '.
You may allocate parameters in a stack. This is done as for ordinary routine calls.

Assemble, load, and execute the program on an ND-500 computer as shown below. No library files are needed. Your input is underlined.

1.7 Monitor Calls in MAC¶

The example below shows how to use monitor calls in a MAC program. MAC is the assembly language for the ND-100. The program copies a file to the terminal, one byte at a time. It waits one second between each character.

)9BEG XCOPY
%Open a file for sequential read.
XCOPY, SAT 1      %Sequential read access in T register.
      LDX (FILNA  %File name pointer in X register.
      LDA (FILTY  %File type in A register.
      MON 50      %Monitor call OpenFile.
      MON 65      %Monitor call ErrorMessage.
      STA FILNO   %Successful OpenFile returns here.

%Read one byte from the file and output on the terminal.
LOOP, LDT FILNO
      MON 1       %Monitor call InByte from file.
      MON 65      %Monitor call ErrorMessage.
      SAT 1       %Logical device number of own terminal.
      MON 2       %Monitor call OutByte to terminal.
      JMP ERR     %Error return, e.g., end of file.

%Make the program wait one second between each character.
      LDA (PAR    %Address of param list to SuspendProgram.
      MON 104     %Monitor call SuspendProgram.
      JMP LOOP    %Read next character.

ERR, LDT FILNO    %Close the file and terminate the program.
      MON 43      %Monitor call CloseFile.
      MON 0       %Monitor call ExitFromProgram.

PAR,  NOTIM       %Address list of SuspendProgram parameters.
      TUNIT

NOTIM, 1          %Number of time units to wait.
TUNIT, 2          %Unit to wait is seconds.
FILNA, 'EXAMPLE-FILE'  %File name.
FILTY, 'DATA'     %File type.
FILNO, 0          %File number.
)FILL
)9END
)LINE

You should note the following with monitor calls in MAC:

Error codes different from 0 cause skip return. That is, the instruction following the monitor call is not executed.
Only the monitor call number can be used in the monitor calls.
Monitor calls only available on the ND-500 cannot be executed.
All string parameters must be terminated with an '.

1.8 Monitor Calls in Other Programming Languages¶

The monitor call libraries are available in BASIC. BASIC programs use monitor calls in exactly the same way as FORTRAN.

Monitor calls may also be used from other languages. In such cases you have to write interface routines yourself. The interface routines are usually written in MAC or ASSEMBLY-500. Assemble the routines. Load them with the main program as any other routine library. The manual describing the language tells you how to transfer parameters.

You may also include MAC or ASSEMBLY-500 statements in PLANC programs.

2.16 Monitor Call Numbers No Longer Supported¶

The following monitor call numbers are no longer in use. They are still available, to allow old programs to be used, but their use is not recommended. In many instances, the function of these monitor calls has been replaced by another.


37B	200B	304B
47B	201B	320B
51B	251B	321B
132B	255B	324B

156B	264B	435B
163B	265B	506B
165B	266B	510B

These monitor calls are not available in the monitor call package. The monitor call package returns -2 as error code when these numbers are used.

2.17 New Monitor Call Numbers¶

Each version of SINTRAN III introduces new monitor calls. Their names are not known by old compilers. The monitor call package allows you to use such monitor calls. You must specify the monitor call number.

Monitor Call Number	Description

Please refer to page 2 for an explanation of how to use this reference.

Page 72¶

AccessRTCommon¶

Reads from or writes to RT common from an ND-500 program. RT common is an area in physical memory where RT programs may exchange data.

Some SINTRAN III systems are generated without RT common. The size of RT common is defined at the time of system generation. The size may be increased by up to 8 pages by the SINTRAN-SERVICE-PROGRAM command DEFINE-RTCOMMON-SIZE (see the SINTRAN III Commands Reference Manual, ND-860128, for more information).

See also GetInputFlags and SetOutputFlags.

PARAMETERS¶

Function. Use 0 to read, and 1 to write.
RT common address. This is a logical ND-100 address in the logical address area of RT common. ND-100 has 16-bit word addresses.
Number of bytes to read or write.
Buffer of data to be read or written.

112B AdjustClock¶

Sets the computer's clock (i.e. the current system time) forward or back. If the operator panel has a clock, it is also adjusted.

The startup time for RT programs can be set by StartupTime. When the current system time is modified, the next startup times of periodic programs started by StartupTime are also affected. Other scheduling times are not affected.

See also SetClock, GetCurrentTime, StartupTime and GetBasicTime.

PARAMETERS¶

Number of time units the clock will be adjusted by. Negative values make the clock halt for the specified time.
The type of time units. 1 = basic time units, i.e. 1/50th of a second, 2 = seconds, 3 = minutes, 4 = hours.

33B ALTPAGETABLE¶

Switches page table. Each page table allows you to access 128 Kbyte memory. SINTRAN III has 4 page tables. SINTRAN III VSX, version K, has 16 page tables. They are numbered 0-15. RT programs may use any page table. Background programs will get page table 2. The parameter is ignored.

The specified page table is used for all later X register relative, B-register relative, and indirect addresses. P register relative addresses go through the normal page table. See the ND-100 Functional Description (ND-06.015) for details on addressing and page table selection.
When used from background, the background segment size must be 256 Kbyte. See @CHANGE-BACKGROUND-SEGMENT-SIZE.
Do not call AltPageTable twice without calling NormalPageTable in between.
If addressing via the alternative page table (LDA, STA), bit 0 in the status register (STS) must be set to 1. If this bit is 0, addressing is via the normal page table. This monitor call sets bit 0 in the status register to 1.
Monitor calls are independent of status bit 0. Return parameters are always on the alternative page table.

PARAMETERS¶

Number of the page table to use.

PASCAL¶

PageTableNumber : INTEGER2;
...
AltPageTable(PageTableNumber);

COBOL¶

240B AppendSpooling¶

Prints a file. The printer has a queue of files waiting to be output. The file is appended to this queue. One or more copies can be printed.

You may connect a text, e.g. INVOICE, to the job. The operator uses the text to select all files to be printed on special paper.
SINTRAN III, version K, allows both the file and the printer to be on remote systems. The complete standard syntax for remote file specification is as follows:
system(user(password:project)).(directory:user)file:type;version

See also CloseSpoolingFile and @APPEND-SPOOLING-FILE.

PARAMETERS¶

→ Name of file to be printed (pointed to by the X-register). The name may be abbreviated.
→ Peripheral file name of the printer (pointed to by the A-register).
→ Number of copies to be printed. Bit 15D set to 1 means that the message in the next parameter should be printed.
← Standard Error Code. See appendix A.

ATTACH500SEGMENT¶

Maps a logical ND-500 data segment onto shared ND-100/ND-500(0) physical memory (multiport memory).

The specified physical memory area must be defined in the "Not initialize page" table by use of the *CHANGE-TABLE command in the SINTRAN Service Program (follow this command by a warm start to put the change into effect). Note that you should not use the first pages of the multiport memory (starting at "ND-500 page 0") for this.

Example:

@SINTRAN-SERVICE-PROGRAM
  *CHANGE-TABLE
  TABLE: MEMORY-AREA-INVISIBLE-FOR-THIS-SYSTEM
  FUNCTION: INSERT-ELEMENT
  IMAGE OR SAVE AREA (DEFAULT IS IMAGE)? IMAGE
  FIRST PAGE (OCT): 10000
  LAST PAGE (OCT): 13777
  FUNCTION: EXIT
  *EXIT

PARAMETERS¶

Function code. 0 = Detach (forget) a previously attached segment.

2nd parameter → Segment number in the range 0–31₁₀.

Function code. 1 = Attach a segment. If a physical segment does not exist, create it and map the segment on to the physical ND-100 address area.

2nd parameter → ND-500 logical data segment address. If you specify 0 (zero), the first free segment will be used.
3rd parameter → Length of segment in pages
4th parameter → ND-100 physical page address

167B AttachSegment REENT¶

Attaches a reentrant segment to your two current segments. The address areas of the segments may overlap. Pages in the reentrant segment may be accessed for reading, writing, or fetching instructions. When written to, a page loses its reentrancy. It is stored on one of your current overlapping segments.

The segment is treated as reentrant only for the RT programs which have attached it.
Parts of the reentrant segment may not be outside the address area of your current segments. OUTSIDE SEGMENT BOUNDS is output if these parts are written to.

PARAMETERS¶

Segment number of the reentrant segment. See @LIST-REENTRANT.

SINTRAN III Monitor Calls¶

121B AwaitFileTransfer WAITF¶

Checks that a data transfer to or from a mass-storage file is completed. The monitor call is relevant to ReadFromFile and WriteToFile operations. These data transfers are carried out independently of the CPU.

You may specify that the program should wait if the transfer is not ready. It is set in the I/O wait state.
A patch exists to permit AwaitFileTransfer to return status information from the last ReadFromFile or WriteToFile. This is a non-standard patch, number 289, available on SINTRAN III VSX and VSX-500.

PARAMETERS¶

File number. See Openfile.
Wait flag. If 0, the program waits until the data transfer is completed. Other values return a value showing the state of the transfer. Programs on the ND-500 do not wait.
State of transfer. Without patch 289: All error codes are from AwaitfileTransfer.
- 0 means that transfer is finished.
- -1 means that transfer is not finished.
- 0 are Standard Error Codes (see appendix A).

With patch 289:

Error Code (SEC)	Description
132₈	No file opened with this number
174₈	Illegal parameter

All other error codes (SEC) are from the last ReadFromFile or WriteToFile.

CallCommand¶

Executes a SINTRAN III command from a program. The program terminates if an error occurs in the command.

You are advised to use the newer monitor call, ExecuteCommand (UECOM), instead of CallCommand.
Some commands may destroy your program. Use care with commands which affect your program's memory area.
Note that the program may terminate if an error occurs. Use ExecuteCommand (UECOM) to avoid this problem.
For commands with output, but without an output file as a parameter, e.g. @WHO, output is displayed automatically on the terminal of the user executing the program.
Use SuspendProgram to wait a specified time interval between two CallCommands which depend on each other, e.g. CreateFile and OpenFile.
The following commands are allowed from ND-500 programs: @DATCL, @COPY, @COPY-FILE, @SCHEDULE, @HOLD, @TERMINAL-MODE, @OPERATOR, @WAIT-FOR-OPERATOR, @SET-TERMINAL-TYPE, @GET-TERMINAL-TYPE, @CREATE-FILE, @EXPAND-FILE, @DELETE-FILE, @RENAME-FILE, @LIST-FILE, @FILE-STATISTICS, @OPEN-FILE, @CONNECT-FILE, @SET-FILE-ACCESS, @CLOSE-FILE, @LIST-OPEN-FILE, @SET-BLOCK-SIZE, @SET-PERMANENT-OPEN, @SET-BYTE-POINTER, @SET-BLOCK-POINTER, @APPEND-SPOOLING-FILE, @DELETE-SPOOLING-FILE, @SET-TEMPORARY-FILE, and @SCRATCH-OPEN.

See also ExecuteCommand and SetCommandBuffer. ExecuteCommand does not terminate the program if an error occurs.

CAMACFunction¶

Operates the CAMAC, i.e. executes the NAF register. CAMAC is a standardized way to connect peripheral equipment to a computer. NAF data looks like this:

15   13     9 8     5 4    0
-----------------------------
|  Q  X  | STATION | SUBADDRESS | FUNCTION |
-----------------------------

If Q=1 and/or X=1, then Q and X responses from the station are automatically checked.

A Control/Status register (COST register) holds some extra information. If the Function parameter is 3 (clear), the contents of COST are returned in the Value parameter. If Function=0 (read), data is returned in Value. For both these functions, parameter 2 must be ≥0 on entry. If Function=1 (write) parameter 2 must be <0 before the call.

If bit 15 in Crate Number is set to 1, Value is treated as an integer instead of floating point.

See also AssignCAMACLAM, BCNAFCAMAC, BCNAF1CAMAC, CAMACIOInstruction, and CAMACGLRegister.

PARAMETERS¶

Value: input of data if write, output if read.
Return status (0 if OK, 24 if not OK).

150B CAMACGLRegister GL¶

Read the CAMAC GL (Graded LAM -"look at me") register or the last CAMAC identification number. See under CAMACfunction (mon 147) for more general information.

When a program requests interrupt, it generates a LAM to the control station. Up to 23 such signals may arrive, but for efficient handling in the computer, these must be reduced to 16 lines called Graded LAMs. The GL register, which may be read by the program, holds a bit mask giving the current LAM requests (bit=1 indicates LAM). The different graded LAM lines have individual IDENT codes (Bits 0-3: Graded LAM code. Bits 4-7: crate code. Bit 8=1 : CAMAC). A LAM Mask Register is used to enable (bit=1) or disable (bit=0) any of the 16 graded LAMs. Each time an IDENT code is read, the associated bit in the MASK register is cleared and must be set by the program to enable a new interrupt.

See also CAMACfunction, AssignCAMACLAM, BCNAFCAMAC, BCNAF1CAMAC, and CAMACIOInstruction.

337B ChangeSegment SPCHG¶

Changes the segment and the page table your program uses. The monitor call is similar to JumpToSegment and ExitFromSegment. In addition, you may change the two page tables in use. The segment numbers are restricted to 8-bits (values 0-255). SegmentFunction (MON 341) is the equivalent monitor call for version K of SINTRAN III.

You cannot change reentrant segments.

See also JumpToSegment and ExitFromSegment, and SegmentFunction.

Parameters¶

Function.

Bit 15 in the D register equal to 0 means JumpToSegment. Bit 0:1 should contain the new alternative page table and bit 2:3 the new normal page table. The T register contains the address of a parameter list. The parameter list consists of the start address and the segment numbers. The execution continues after this monitor call when an ExitFromSegment function is performed. The D register then contains the old page tables.

Bit 15 in the D register equal to 1 means ExitFromSegment. Bit 0:1 should contain the old alternative page table and bit 2:3 the old normal page table.

CloseFile¶

Closes one or more files. Files must be opened before they are accessed. Afterwards they should be closed.

CloseFile also resets peripheral files. This is similar to DeviceControl with control flag -1.
For non-RT programs, files are closed when your program terminates.

See also OpenFile, CloseSpoolingFile, BackupClose, and @CLOSE-FILE.

Parameters¶

File number returned when the file was opened. Use -1 to close all your files which are not set permanently open. The block size of all scratch files which are permanently opened is set to 400B. Use -2 to close all your files, including your scratch file and those files set permanently open.

251B CopyPage Copag¶

Copies file pages between two opened files. One of the files may be a magnetic tape or floppy disk with volume.

This is a special monitor call used by the BACKUP-SYSTEM. No high-level language interface exists. The use of the X and D registers is tailored for reading labels on magnetic tape.
Copying stops at end-of-file, a non-existent page, or if a short magnetic tape record is found.
CopyPage is only used for sequential copying, i.e., a sequence of CopyPage calls must start with page number zero.
Files should be opened for random read or write.
Both files must be local files.

Parameters¶

File number of source file in the T register. Use logical device number for magnetic tape and floppy disks.
File number of destination file in the A register. Use logical device number for magnetic tapes and floppy disks.
Address of 32-bit word with page address of first page to copy. The page address is the same for the source and destination files.
Address of buffer to receive short magnetic tape record if source file is magnetic tape. Use -1 if you do not want the short record returned.

Output parameters if normal return:¶

Error number relating to the destination file in the A register. See appendix A.

Output parameters if skip return:¶

Error number relating to the source file in the A register. If finished, end-of-file is returned. See appendix A.

Output parameters if double skip return:¶

Unless the source is magnetic tape, a page is missing.

Page number of the missing page in the A&D register.
A set of contiguous pages can be missing. The T and X register contains the last page number missing in such a hole. This is only returned if the source is a directory.
Number of 16-bit integers returned if a short magnetic tape record is found. Only for magnetic tape as source and the D register different from -1.

221B CreateFile CRALF¶

Creates a file. The file may be indexed, contiguous, or allocated. Most files are indexed. The size of indexed files expands automatically when written to. Contiguous and allocated files have shorter access time.

You need directory access to the user who owns the file.
User SYSTEM and RT always have the owner's access rights.
An indexed file not yet written to may be converted to a contiguous file. Use ExpandFile or @EXPAND-FILE.

See also @CREATE-FILE, @ALLOCATE-FILE, NewFileVersion, and ExpandFile.

PARAMETERS¶

File name. Default file type is :DATA.
Start address in the directory. Use 0 if you want to create a contiguous or indexed file.
Length of the file in pages. Use 0 if you want to create an indexed file.

DATA TRANSFER¶

Transfers data between physical memory and a mass-storage device, e.g. a disk or magnetic tape. You may perform various device control functions. This monitor call is mainly used by the operating system itself. For more details, refer to the ND-100 SCSI Reference Guide, ND-12.048.

With SINTRAN III/VSX, the monitor call and the parameters must reside on a fixed segment on protection ring 2. With SINTRAN III/VSE, the monitor call and parameters must reside in resident memory.
The physical memory area must be contiguous. Older versions of magnetic tapes or disk controllers cannot cross physical memory bank boundaries of 128 Kbytes. These magnetic tapes have ND numbers less than ND-537. The disks have ND numbers less than ND-559.
If you write code to be independent of whether it is run on SINTRAN III VSE or VSX, you are advised to use TransferData (EXABS, mon 335).

See also TransferData, ReadFromFile and WriteToFile. TransferData allows you to use any page table.

PARAMETERS¶

Logical device number. See appendix B.
Function code. See the tables on the following pages.
Physical memory address.
Block address on the disk. See the tables on the following pages.
Number of blocks to transfer.
Error code. Negative if error. Contains a hardware status.

The call formats are marked from a-i. All formats give status on return. See appendix A. The return status >=0 means the call terminated correctly. Parameters which do not affect the call format are called "dummy" below. All call formats contain logical unit number (0-3) in function code bits 6-8.

The call format "a" is:¶

Status=ABSTR(logical device number, Unit/function code, dummy, dummy, dummy)

The hardware status is returned as error code. The device must be reserved. Otherwise a positive error code may not be the correct hardware status.

The call format "b" is:¶

Status=ABSTR(logical device number, Unit/function code, dummy, dummy, dummy)

Status is Standard Error Code.

The call format "c" is:¶

Status=ABSTR(logical device number, Unit/function code, physical memory address, sector address, no of sectors to read)

The call format "d" is:¶

Status=ABSTR(logical device number, Unit/function code, physical memory address, sector address, no of sectors to write)

The call format "e" is:¶

Status=ABSTR(logical device number, Unit/function code, dummy, dummy, floppy format number)

The call format "f" is:¶

Status=ABSTR(logical device number, Unit/function code, dummy, dummy, sector address)

The call format "g" is:¶

Status=ABSTR(logical device number, Unit/function code, dummy, dummy, destination unit number)

SINTRAN III Monitor Calls¶

The call format "h" is:¶

Status=ABSTR(logical device number,Unit/function code,dummy,dummy,first sector address of track)

The call format "i" is:¶

Status=ABSTR(logical device number,Unit/function code,physical memory address,dummy,dummy)

Format code is returned in physical memory address.

The call format "j" is:¶

Status=ABSTR(logical device number,Unit/function code,physical memory address,dummy,dummy)

Disk layout table (8 words) is returned in physical memory address.

DefaultRemoteSystem¶

Sets default values for COSMOS remote file access. You can specify the default remote system, the remote user, and the remote user's passwords. The specified values are used when you omit values in a remote file access.

Empty parameters remove previous default values. Default values are then the local user's name and passwords.
SetRemoteMode switches the remote search on and off.

See also @SET-DEFAULT-REMOTE-SYSTEM and @RESET-DEFAULT-REMOTE-SYSTEM.

Parameters¶

DeviceControl¶

Sets control information for a character device, e.g. a terminal or a printer. The control information depends on the device.

The device must be reserved. See ReserveResource.

Parameters¶

Logical device number. See appendix B. You cannot use 1 for your own terminal. Use ExecutionInfo to get its logical device number instead. File numbers are illegal.
Input or output part of the device. Use 0 for input and 1 for output.
Address of RT description of reserving program. Use 0 for the calling program.
Control flag. Use -2 to empty the TAD output buffer. Use -1 to reset the device. This sets card readers in ASCII mode. 0 sets ASCII mode without resetting the device. 1 sets binary mode. InByte will then return a 12-bit card column image.
Return status. 0 means no errors. An illegal RT description address returns -1.

Call formats:¶

The call formats are marked from a-i. All formats, except "a", give the Standard Error Code as return status. See appendix A. The return status 0 means the call terminated correctly. Parameters which do not affect the call format are called "dummy" below.

The call format "a" is:¶

DeviceFunction(function code,dummy,logical device no.,dummy,dummy)

The hardware status is returned as error code. The device must be reserved. Otherwise a positive error code may not be the correct hardware status.

The call format "b" is:¶

DeviceFunction(function code,dummy,logical device no.,dummy,dummy)

The call format "c" is:¶

DeviceFunction(function code,array name,logical device number, maximum numbers of words or bytes,numbers of words/bytes read)

The call format "d" is:¶

DeviceFunction(function code,array name,logical device number, number of words or bytes to be written,dummy)

The number of words to be written is rounded off to whole 16-bit words.

The call format "e" is:¶

DeviceFunction(function code,dummy,logical device number, density/parity,dummy)

density/parity
0	1600 BPI
1	6250 BPI
2	800 BPI
	or 800, 1600 or 6250.

The call format "f" is:¶

DeviceFunction(function code,dummy,logical device number, input format,dummy)

DMAFUNCTION¶

Performs various DMA functions. Most functions transfer data between your memory area and a DMA channel.

The output part of the DMA channel must be reserved. See ReserveResource. Do not reserve the input part.
RT programs may fix the segment which holds the memory buffer contiguously. See FixContiguously. The data is transferred directly into the memory buffer.
No Wait can only be used from ND-500 or if the segment is fixed contiguously.

PARAMETERS¶

Logical device number of a DMA channel.
Function code. See the next page.
Memory address of data to send or receive for function code 0:3. Function codes 54:57 use programmed input/output devices. Then this parameter contains the logical device number of the device. The parameter is ignored for other function codes.
Input parameter. Function dependent. See the next page.
Output parameter. Function dependent. See the next page. Some functions return a status value. Bits 0:7 and bit 15 are copied from the device status word. Bits 8:14 are user status lines. Bit 16 means that an DMA interrupt has occurred. Bit 17 means timeout.

126B ExactDelayStart¶

Sets an RT program to start after a given period. It is then moved from the time queue to the execution queue. The period is specified in basic time units. A basic time unit is 1/50th of a second. The period may be from 1 to 4294967647 basic time units.

The program may already be in the time queue. It is then reinserted according to the new specifications.
A period less than or equal to 0 transfers the RT program to the execution queue the next time the basic time unit counter is incremented.
SetClock, AdjustClock and @CLADJ do not affect the interval.
StopRTProgram removes the RT program from the time queue.

See also DelayStart and StartupTime. DelayStart allows you to specify the period in seconds, minutes, and hours.

ExactInterval¶

Prepares an RT program for periodic execution. The interval between the executions may be from 1 to 4294967647 basic time units. A basic time unit is 1/50th of a second.

The RT program is not started. Use, for example, StartRTProgram or @RT to start it.
StopRTProgram, Disconnect, @ABORT or @DSCNT cancel this monitor call.
One execution may be unfinished when it is time for the next execution. In this case, the program's restart flag is set. If the delay becomes as long as two intervals, one execution is lost.
The interval replaces any earlier specified intervals.
AdjustClock and @CLADJ do not affect the interval.

See also StartupInterval and @DINTV. StartupInterval allows you to specify intervals in seconds, minutes or hours.

143B ExecutionInfo RS10¶

Gets information about the execution of the calling program. You are told whether the program executes interactively, as a batch or mode job, or as an RT program. The monitor call returns some additional information for non-RT programs, consisting of the command input file, the command output file, and the directory index and user index of the program's owner.

Your terminal number is returned as the command input and output files in interactive programs.

Parameters¶

Execution mode.
- 0 means interactive program
- 1 means batch job
- 2 means mode job
- 3 means RT program

Logical device number for command input. This is your terminal number for interactive programs. Batch and mode jobs return the file number of the command input file. Not used for RT programs.

Logical device number for command output. This is your terminal number for interactive programs. Batch and mode jobs return the file number of the command output file. Not used for RT programs.

Directory and user index of the program's owner. On the ND-100, the Directory Index is the uppermost 8 bits and the User Index is the lowermost 8 bits. On the ND-500, the Directory Index is the uppermost 8 bits of the lowermost halfword. i.e. bits 8-15, and the User Index is the lowermost 8 bits, i.e. bits 0-7, (the uppermost halfword, bits 16-31, is zero - i.e. all bits are cleared). Not used for RT programs.

133B ExitFromSegment MEXIT¶

Exchanges one or both current segments. Commonly used to return after the monitor call JumpToSegment. ChangeSegment may be used instead of JumpToSegment and ExitFromSegment. The segment numbers are restricted to 8-bits (values 0-255). Use SegmentFunction (MON 341) with version K of SINTRAN III.

The L register must contain the return address. This makes the monitor call complicated to use in high level languages.

See also JumpToSegment, ChangeSegment and SegmentFunction.

PARAMETERS¶

Segment numbers. The most significant byte of this 16-bit integer contains the first segment number. The next byte contains the second segment number. If you only want to change the first segment, use 377B for the segment you do not want to change.

412B FileAsSegment FSCNT¶

Connects a file as a segment to your domain. You can then access the file as a logical segment. This reduces the access time.

The file must be open. The access must be specified in the OpenFile call.
The file is disconnected when it is closed.
A file may be connected to several processes simultaneously. It is your responsibility to synchronize simultaneous accesses.
You may not use ReadFromFile (mon 117) or WriteToFile (mon 120) on a file which is connected to a segment. Refer to these monitor calls for further details.

See also FileNotAsSegment which disconnects the file.

PARAMETERS¶

File number. See OpenFile.
Logical segment number in the domain. The segment number must be free. Use 0 to select the first free segment. The last parameter returns the logical segment number.
Access type. Use 0 if the file contains initial data. 1 means uninitialized, empty file. 2 means primarily sequential access. Use 3 for a combination of 1 and 2. Type 2 reduces the access time if access is sequential.
Logical segment number selected if you give 0 in the second parameter.

160B FIXCONTIGUOUS `FIXC`¶

Places a segment in physical memory. Its pages will no longer be swapped to the disk. The segment is placed in a contiguous area of physical memory. This function is useful for time-critical operations.

The segment must be created with the RT LOADER as a non-demand segment.
Use UnfixSegment or @UNFIX to allow the RT LOADER to clear the segment.
Your program normally terminates if you refer to a nonexistent segment or a demand segment. An error message is output on the error device. See parameters 1 and 3 to get a status value instead.
Only a limited number of pages can be fixed. This limit is defined when SINTRAN III is generated. You may change it with the command CHANGE-VARIABLE in the SINTRAN-SERVICE-PROGRAM.

See also UnfixSegment, FixScattered, FixInMemory, MemoryAllocation, FixIOArea, and @FIXC.

PARAMETERS¶

Segment number to be fixed. Set bit 15 to 1 if you want a return status.
First physical page number to be used.
Return status if bit 15 of the segment number is set. Dummy on the ND-500. 0 means OK. -1 means space not available. -2 means illegal segment. -4 means attempt to fix demand segment. -5 means attempt to fix too many pages. -6 means segment already fixed at another address.

410B FIXINMEMORY¶

Fixes a logical segment of your domain in physical memory. You can fix the whole or part of the segment. This speeds up access to the segment. It is also useful in segment sharing.

Only data segments may be fixed.

PARAMETERS¶

Type of fixing. 0 means fix the pages scattered. 1 means fix the pages contiguously and return the start address. 2 means fix at the given memory address.
Start address in your domain. It should be a 32 bit address including the segment number.

ForceRelease¶

Releases a device reserved by an RT program other than that which is calling. You can then reserve the device for your own RT program. Some devices, such as terminals, have both an input and output part. You can only release one part with each ForceRelease.

Use ReservationInfo to get the RT description address of the reserving RT program. You may then give the device back with ForceReserve.
Programs in a waiting queue may reserve the device between your ForceRelease and ReserveResource calls if they have higher priority than your program.
The SINTRAN III Real Time Guide (ND-860133) describes this in more detail.

See also ForceReserve, ReleaseResource, and @PRLRS.

124B FORCE RESERVE¶

Reserves a device for an RT program other than that which is calling. Use ForceRelease if the device is already reserved.

You can only release peripheral devices, such as terminals and printers, and semaphores in this way.
Programs in a waiting queue may reserve the device between your ForceRelease and ForceReserve calls if they have higher priority than your program.
The SINTRAN III Real Time Guide (ND-860133) describes this in more detail.

See also ForceRelease, ReserveResource, and @PRSRV.

PARAMETERS¶

Logical device number. See appendix B.
Input or output flag. Use 0 for the input part and 1 for the output part.

Gets information about why the last ND-500 program terminated. There are five parameters for each background user. These can be set by SINTRAN III or your background program.

Use SetND500Param to set the parameter values.
SINTRAN III sets some of the parameter values if you give the command @ENABLE-TERMINATION-HANDLING first.

See also TerminationHandling, SetND500Param, GetUserParam, and SetUserParam.

PARAMETERS¶

The five user parameters as an array. SINTRAN III's termination handling returns the following:

Parameter	Description
1	Bit 24:16 contain the user index. Bit 7:0 contains the directory index.
2	Logical device number of the terminal.
3	Fatal error or the monitor call ErrorMessage returns the error number. If escape was pressed, -1 is returned.
4	User defined.
5	User defined.

The parameters are returned if the user presses the ESCAPE key, if the monitor calls ExitFromProgram or ErrorMessage are executed, or if a fatal error occurs. All parameters can be user defined if no termination handling is enabled.

57B GetUserParam PAGET¶

Gets information about why the last program terminated. There are 5 parameters for each background user. These can be set by SINTRAN III or your background program.

Use SetUserParam to set the parameter values.
SINTRAN III sets some of the parameter values if you give the command @ENABLE-TERMINATION-HANDLING first.

See also TerminationHandling, GetND500Param, @DEFINE-TERMINATION-HANDLING, @DISABLE-TERMINATION-HANDLING, and @SET-USER-PARAMETERS.

PARAMETERS¶

The five user parameters. This is an array of 16-bit integers on the ND-100. ND-500 returns an array of 32-bit integers. SINTRAN III's termination handling returns the following:

Parameter	Description
1	The last byte contains the user index. The byte in front of it contains the directory index.
2	Logical device number of the terminal.
3	Fatal error or the monitor call ErrorMessage returns the error number. If escape was pressed, -1 is returned.
4	User defined.
5	User defined.

The parameters are returned if the user presses the ESCAPE key, if the monitor calls ExitFromProgram or ErrorMessage are executed, or if a fatal error occurs. All parameters can be user defined if no termination handling is enabled.

HDLCFunction¶

Performs various HDLC functions. A HDLC is a high-level data link to another computer. You may send data, receive data, and control HDLC. Data is sent as Driver Control Blocks (DCB). This monitor call is also used by X.21 to transfer DCBs between the user programs and the X.21 driver. The system uses the Logical Device Number to distinguish between HDLC and X.21.

Use MON 122, ReserveResource, and MON 123, Release Resource for exclusive access to a LDN.

Parameters¶

Function code: Use 0 to send DCB to driver and 1 to receive DCB from driver
Logical device number: There are different logical device numbers for the input and output part. See appendix B.
Address of driver control block: The first word in the DCB contains command information. The commands are:
1. Transfer frame data (TRANS)
2. Reset logical device (RESET)
3. Device clear (DEVCL)
4. Device initialization (DEVINI)
5. Get device status (DEVSTA)
  The second and third words contain status information, while the rest may contain frame data or additional information, depending on the command in the first word.
Size of the used part of the driver control block in bytes.
Depends on the function code: maximum size of the driver control block in bytes for the SEND function, wait flag for the RECEIVE function. The program waits for a driver control block if 1. Use 0 to make the program continue.
HDLC error code:
- -1: LDN not reserved by calling program.
- -2: Illegal LDN. Not known by SINTRAN.
- -3: No DCB in receiver queue.
- -4: No vacant buffer for DCB.
- -5: Illegal used DCB size (parameter 4).
- -6: Illegal LDN. Not permitted from this monitor call.
- -7: Max. DCB size (parameter 5) is less than used DCB size.
- -10: Illegal function.

InByte¶

Reads one byte from a character device, e.g. a terminal or an opened file. If the device is a word-oriented device, one word is read. This monitor call can be used on most input devices.

Bit 7 is a parity bit if terminal or file input. IOMultiFunction may change this.
The program waits if there is no bytes in the input buffer of the device. You can change this with NoWaitSwitch or TerminalNoWait.
The pointer to the next byte is incremented when you read from a mass-storage file.
Input from card readers are converted to ASCII characters. Use DeviceControl to read the 12-bit card columns.
Background programs may read from logical device number 0. This is the SINTRAN III command buffer. You may read parameters following the program name this way. Break and echo are both set to 1. Normal SINTRAN III command editing is available. All letters are converted to uppercase. You may control this with IOMultiFunction.
Appendix F contains an ASCII table.

See also In8AndFlag, InUpTo88Bytes, In8Bytes, InString, InputString, In4x2Bytes, and OutByte.

Parameters¶


⟶	Logical device number. See appendix B. Use 1 for your own terminal.

161B INSTRING¶

Reads a string of characters from a peripheral device, e.g. a terminal.

Background programs wait if there are no characters in the device buffer. RT programs continue.
All parameters are fetched and returned via the alternative page table.
You are advised to use the faster InputString on the ND-500.
Appendix F contains an ASCII table.

See also InputString, In8AndFlag, InUpTo8Bytes, In8Bytes, In4x2Bytes, and OutString.

PARAMETERS¶

Parameter	Description
DeviceNo	Logical device number of a peripheral device. See appendix B.
TextRead	String of characters.
NoOfBytes	Maximum number of characters to be read.
Terminator	Terminating character. Input stops when this character is read.
ReturnStatus	A 16-bit integer status. Errors in parameters return -1. If bit 15:14 is 0, the maximum number of characters is read. If 1, a termination character is read. 2 means not terminated. This applies only to RT program. 3 means device error. Bit 7:0 contains the error number. If bit 15:14 are 0, 1 or 2, the number of characters read is returned in bit 13:0.

132B JumpToSegment MCALL¶

Calls a routine on another segment in the ND-100. You can divide an ND-100 RT program between various segments. This monitor call switches one or both of the current segments according to what you specify in parameter 2. ChangeSegment may be used instead of JumpToSegment and ExitFromSegment. The segment numbers are restricted to 8-bits (values 0-255). Use SegmentFunction (MON 341) with version K of SINTRAN III.

Use ExitFromSegment to return from the routine.
JumpToSegment may be nested.
This monitor call does not change reentrant segments.

See also ExitFromSegment, ChangeSegment and SegmentFunction.

PARAMETERS¶

Address of routine.
New segments. The most significant byte identifies the first segment. The least significant byte identifies the second segment. Use 377B as segment number if you do not want to change it. The RT description identifies the segments which are current.

315B LAMUFunction MLAMU¶

Performs various functions on the LAMU system. A LAMU is a logically addressed memory unit. The LAMU system is an extension to the ND-100 segment structure. Programs may address more space than provided by the 3 available segments.

Several CPUs may share the same LAMU address space.
The monitor call is implemented in Pascal as 10 separate routines, each corresponding to one function code. In all other languages, it is presently implemented as one routine, to which you pass the function code as the first parameter. This may change in the future, i.e. separate routines may be added.

PARAMETERS¶

Function code.
- 1 means create a LAMU.
- 2 means delete a LAMU.
- 3 means connect a LAMU to the calling program or another program.
- 4 means disconnect a particular LAMU or all LAMUs from the calling program or another program.
- 7 means protect LAMU.
- 8 means get LAMU information.
- 9 means create system-LAMU.
- 10 means create temporary system LAMU and connect it to the calling program.

FUNCTION CODE 1: CREATE A LAMU.¶

Allowed in RT programs (ring ≥ 1), and in all programs run by users RT and SYSTEM.

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number.
- = 0: The system will select a LAMU ID number. Its value will be returned in this parameter.
- 0: The LAMU will be identified by the number given, if the number is previously unused and within the legal range (1 ≤ ID ≤ MAX), where MAX is a value set at SINTRAN(^0) generation time, or by the SINTRAN Service Program or S3-CONFIG. The current maximum value can be listed by the command LIST-LAMU-CONSTANTS in SINTRAN Service, or by choosing the LAMU menu option in the S3-CONFIG program.

Parameter 3: Size. The number of pages in the LAMU. The legal range is 1 to 200
Parameter 4: Physical page.
- = 0: The system will select the first LAMU memory area large enough for the LAMU. The first physical page number of the area will be returned.
- 0: Specifies the first physical page of the LAMU. Legal values include all physical pages currently used as LAMU areas, remembering that there must be room for the whole LAMU in the LAMU area (i.e., you must consider size, and not pick a first physical page too near the end of the LAMU area).

FUNCTION CODE 2: DELETE A LAMU.¶

The LAMU will be deleted if it is not in use by other programs. The physical pages used in the LAMU will remain in LAMU area. Allowed in RT programs and in all programs run by users RT and SYSTEM (ring ≥ 1).

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number.
- Specify the LAMU to be deleted.

Parameter 3: Dummy.
Parameter 4: Dummy.

Page 333¶

SINTRAN III Monitor Calls¶

FUNCTION CODE 3: CONNECT A LAMU TO THE CALLING PROGRAM OR ANOTHER PROGRAM¶

The specified LAMU will be inserted in the address area of the specified program. Allowed in all programs and for all users.

The maximum number of LAMU's a program can have connected to it is decided at system generation time, or later by the SINTRAN Service Program command SET-LAMU-CONSTANTS or by the S3-CONFIG program. A connected LAMU must not overlap in logical address area with any other connected LAMU. The LAMU may overlap some of the current segments or RT common, but the LAMU must then be disconnected if access to the segment or RT common is intended. The connected LAMU will be disconnected by the Disconnect LAMU function (function code 4) in this monitor call. For RT programs, the connected LAMU is also disconnected by StopRTProgram, the SINTRAN command @ABORT, or the command DELETE-PROGRAM in the RT Loader. For background programs, the connected LAMU is also disconnected when the user running the program logs out.

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number. Specify the LAMU to be connected to the program.
Parameter 3: Address of the RT description of the program to which the LAMU should be connected.

Value	Description
0	The calling program. Zero must be used for background programs, thus you cannot connect a LAMU to a background program other than the calling program.
> 0	Address of the program's RT description.

Parameter 4: Logical page. The first logical page used to address the LAMU. The legal range is 100 - 277. Values 100 - 177 result in use of page table 1, whereas values 200 - 277 result in use of page table 2. The logical page number can be computed from the physical address as follows:

[ LP_8 = \left(\frac{PA_8}{2000_8}\right) + (PT_8 \times 100_8) ]

where:
- LP = logical page
- PA = physical address
- PT = page table number (1 or 2)

Note that PA must be exactly divisible by 2000.

Page 334¶

FUNCTION CODE 4: DISCONNECT A PARTICULAR LAMU OR ALL LAMU'S FROM THE CALLING PROGRAM OR ANOTHER PROGRAM.¶

Allowed in all programs and for all users.

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number.
- = -1 Disconnect all LAMU's connected to the program.
- -1 Disconnect the specified LAMU.
Parameter 3: Address of the RT description of the program from which the LAMU should be disconnected.
- = 0 The calling program. Zero must be used for background programs, thus you cannot disconnect a LAMU from a background program other than the calling program.
- 0 Address of the program's RT description.
Parameter 4: Dummy.

FUNCTION CODE 7: PROTECT A LAMU.¶

Allowed in RT programs (ring ≥ 1), and in all programs run by users RT and SYSTEM.

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number.
- Specify the LAMU to receive protection.
Parameter 3: Protection.
- Bits 9-10: Program ring. Use of the LAMU by programs with a value greater than or equal to the specified value is permitted.
- Bit 13: Fetch permitted (1) or not permitted (0).
- Bit 14: Read permitted (1) or not permitted (0).
- Bit 15: Write permitted (1) or not permitted (0).
Parameter 4: Dummy.

FUNCTION CODE 8: GET LAMU INFORMATION.¶

Allowed in RT programs (ring ≥ 1), and in all programs run by users RT and SYSTEM.

Parameter 1: Function code.
Parameter 2: LAMU ID (identification) number.
- Specify the LAMU to get information about.
Parameter 3: LAMU information. Three word array containing the following information:
- Word 1: the first physical page used by the LAMU
- Word 2: the number of pages in the LAMU
- Word 3: the LAMU protection information
Parameter 4: Dummy.

NoWaitSwitch¶

Switches No Wait on and off. No Wait is useful for input from, and output to several devices simultaneously. In No Wait, the program does not wait for input or output to complete. Monitor calls like InByte return error code 3 instead.

SuspendProgram or WaitForRestart may passivate the program afterwards. The program restarts when input or output to the device is completed.
For performance reasons, use TerminalNoWait (TNOWAI, mon 307) rather than NoWaitSwitch.

See also InByte, OutByte, and TerminalNoWait.

Parameters¶

Parameter Description
Logical device number of a character device. See appendix B.
Input or output flag. Use 0 for input and 1 for output.
No Wait flag. Use 0 to switch No Wait off, and any other number to switch it on.

303B OffEscLocalFunction ELOFF¶

Delays the escape and local functions for your terminal. Then the ESCAPE key or LOCAL key does not terminate a program or remote connection immediately. Their functions are delayed until OnEscLocalFunction is executed.

Enable the escape and local functions again by OnEscLocalFunction.
If both the ESCAPE and the LOCAL keys are pressed, local is executed on OnEscLocalFunction.
This monitor call is used to protect critical instruction sequences.

SINTRAN III Monitor Calls¶

50B OpenFile OPEN¶

Opens a file. You cannot access a file before you open it. Specify what kind of access you want, e.g. sequential write or random read.

CloseFile closes the file.
Opened files are closed when a program terminates.
You may have a maximum of 18 files opened at a time.
Files are protected from access by unauthorized users. Use @FILE-STATISTICS to list the file access.
ND-500 has its own file numbers which may differ from the SINTRAN III file numbers.

See also ScratchOpen, SetPermanentOpen, DirectOpen, and @OPEN-FILE.

Parameters¶

← (↔ from ND-500) File number (=LDN for peripheral files). Monitor calls for input and output use this number. From ND-500, this parameter must be initialized (ordinarily to zero) before the call is made.

→ Access code. The legal values are shown below.

Code	Description
0	Sequential write.
1	Sequential read.
2	Random read or write.
3	Random read only.
4	Sequential read or write.
5	Sequential write append.
6	Random read or write common on contiguous files.
7	Random read common on contiguous files.
8	Random read or write on contiguous files. Direct transfer for ReadFromFile, WriteToFile and DeviceFunction in RT programs.
9	Random read, write append for WriteToFile.

→ File name. Unabbreviated file names are most efficient. The name must be terminated with an apostrophe (e.g. MY-FILE:TEXT').

→ Default file type. Do not include the colon.

← Standard Error Code. See appendix A.

67B OutBufferSpace OSIZE¶

Gets the number of free bytes in the output buffer (number of bytes which can be written before the program must wait). Terminals and other character devices place output in a buffer. Monitor calls like OutByte writes to this buffer.

Use ExecutionInfo to get the logical device number for terminals. You can specify 1 for your own terminal.
This monitor call is not available for internal devices. Use InBufferSpace and subtract this size from the inbuffer size.

See also ClearOutBuffer and InBufferSpace.

OutByte¶

Writes one byte to a character device, e.g. a terminal or an opened file. If the device is a word-oriented device, one word is written.

The program waits if the output buffer of the device is full. You can change this with NoWaitSwitch or TerminalNoWait.
The pointer to the next byte is incremented when you write to a mass-storage file.
Output from card readers are converted to ASCII characters. Use DeviceControl to write the 12-bit card columns.
You are advised to use the faster OutputString on the ND-500.
Appendix F contains an ASCII table.

See also OutUpTo8Bytes, Out8Bytes, OutString, OutputString, OutMessage, OutNumber, and InByte.

504B OutputString¶

Writes a string to a device, e.g. a terminal or an opened file.

This is the most efficient way to output strings on the ND-500.
The maximum string length is 2048 bytes.
Appendix F contains an ASCII table.

See also OutMessage, OutUpTo8Bytes, Out8Bytes, OutString, OutNumber, OutByte, and InputString.

PARAMETERS¶

Description
Logical device number, e.g. a file number. See appendix B. You may use 1 for your own terminal. Use the SINTRAN III open file number if output to a file. The ND-500 open file number will not function.
Number of bytes to write.

162B OutString¶

Writes a string of characters to a peripheral file, e.g., a terminal or a printer.

You cannot use this monitor call for mass-storage files.
The output buffer of the device may be too small. Then the program waits until the required buffer space becomes available.
Parameters are fetched and returned through the alternative page table.
The maximum string length is 2048 bytes (as in OutputString).
For performance reasons, it is inadvisable to use this call from the ND-500(0). Use OutputString instead.
Appendix F contains an ASCII table.

See also OutMessage, OutUpTo8Bytes, Out8Bytes, OutputString, OutNumber, OutByte, and InString.

PARAMETERS¶

Logical device number. See appendix B. You cannot use 1 for your own terminal. Use ExecutionInfo to get its logical device number instead. File numbers are illegal.
Character string to be output.
Number of characters to be output.
Return status:
-1 means error in parameters.
0 in bit 15:14 means OK.
2 in bit 15:14 means that the number of characters is greater than the output buffer of the device. The program has to wait. This does not apply to terminals and communication channels.
3 in bit 15:14 means device error. Bit 7:0 contains the error number.

117B ReadFromFile RFILE¶

Reads any number of bytes from a file. The read operation must start at the beginning of a block. The file must be opened for random read access.

The standard block size is 512 bytes. You can change this with SetBlockSize. The first block is number 0.
You may use access code D for direct transfer. Then the block size must be a multiple of the page size. The number of bytes to transfer must be a multiple of the block size.
Peripheral files are always read sequentially.
Data transfer across segment or RT common limits is illegal as this would be likely to result in inconsistent data.

See also SetStartBlock, SetBlockSize, ReadDiskPage, ReadBlock, WriteBlock, and WriteToFile.

PARAMETERS¶

Parameter	Description
File number	See Openfile.
Wait flag	Use 0 to suspend the program until the transfer is completed. Other values make the program continue. You may check that the transfer is completed by AwaitFileTransfer.

212B ReentrantSegment¶

Connects a reentrant segment to your two current segments. All modified pages of your current segments are written to the segment file before the reentrant segment is fetched. This is almost equivalent to SaveSegment followed by AttachSegment. However, ReentrantSegment is more efficient. Only the modified pages overlapping the reentrant segment are written back.

Parameters¶

Segment number to attach.

341B SegmentFunction SGMTY¶

This is a multifunction monitor call used to change the active segments of a program, or the page index tables used by a program.

This monitor call is meant to replace the older calls ChangeSegment (SPCHG, 337), and JumpToSegment (MCALL, 132) and ExitFromSegment (MEXIT, 133) on the VSX version.
In ChangeSegment, JumpToSegment and ExitFromSegment, the segment numbers are limited to 8 bits (values 0-255). With the monitor call SegmentFunction, the segment numbers are 16 bits (values 0-65535).
The functionality of the calls MCALL and MEXIT is expanded so as to allow you to change (or not) the page index table to be used with the new segment.
A new function has been introduced in this call, that of removing a routine from being a direct task or a device driver, which has been entered as such by the monitor call SegmentToPageTable (ENTSEG).

See also ChangeSegment, JumpToSegment and ExitFromSegment.

PARAMETERS¶

Function code.
- 0 = JumpToSegment (MCALL) without PIT change
- 1 = ExitFromSegment (MEXIT) without PIT change
- 2 = JumpToSegment (MCALL) with PIT change
- 3 = ExitFromSegment (MEXIT) with PIT change
- 4 = REMSG (remove segment entered by ENTSEG)

For function 4 (REMSG), parameters 2 (ADDR), 4 (SEG2), and 5 (PITS) must be zero.

Start/return address
New segment 1
New segment 2
New page index tables

The values returned in the following registers depend on the function in parameter 1:

Function	Register
Functions 0 and 2	(MCALL):
T	Old segment 1
D	Old segment 2
L	Return address
X	Old PITs if PITs changed (function 2)
Functions 1 and 3	(MEXIT): No register change
Function 4	(REMSG): A = 0 : ok
	-1 : segment not entered
	-2 : illegal segment number
	-3 : no segments entered
	-4 : illegal parameter

323B SegmentOverlay¶

Used to build multisegment programs in the ND-100. It is mainly for internal use. A new reentrant segment and two address areas in this segment are specified.

The building of multisegment programs is taken care of automatically by the BRF-LINKER. See the BRF-LINKER USER MANUAL (ND-860196).

PARAMETERS¶

Segment number. The segment must be reentrant.
Page number of first page in address-area 1. Normally in the program bank.
Number of pages in address-area 1.

157B SegmentToPageTable ENTSG¶

Enters a routine as a direct task or as a device driver, and "remembers" which segments have been entered (up to 24 segments). These are reentered at restart following a power failure. The routines are connected to the interrupt system. They are loaded with the RT LOADER or by DMAC.

The segment where the routine resides must be fixed in memory. See FixScattered.
The segments can be removed from the selected PIT by using function 4 of ChangeActiveSegments (MON 341).
Unfixing the segment (using UnFixSegment, MON 116), removes it from the Page Index Table.

PARAMETERS¶

Segment number where the routine resides.
Page table to use for the segment. In practice, this should be 3. For SINTRAN III VSX, version K, the range is 0-17.
The interrupt level where the direct task should run. You must specify one of the free levels 6, 7, 10B or 11B. Do not use level 2B on SINTRAN III VSX, version K.
Start address of the routine (entry point).
Error code in A-register = 0 : OK

Code	Explanation
-1	attempt to enter too many segments
-2	illegal segment number
-3	illegal Page Index Table
-4	segment is not fixed
-5	illegal interrupt level
-6	PIT already in use

76B SetBlockSize SETBS¶

Sets the block size of an opened file. Monitor calls which read randomly from, or write randomly to a file, operate on blocks. See ReadFromFile and WriteToFile.

The standard block size is 512 bytes. This block size is set when the file is opened.
The block size is reset when the file is closed.
Factors of 2048 bytes are the most efficient block sizes.

See also SetStartBlock, ReadFromFile, WriteToFile, and @SET-BLOCK-SIZE.

PARAMETERS¶

SetBreak¶

Sets the break characters for a terminal. Normally, a program waits for input. When a break character is typed, the program restarts. For example, most subsystems restart when you press the RETURN-key after a command. The subsystems have defined the RETURN-key as a break character.

SINTRAN III has some predefined break tables.
You may define your own break table. This is a 128-bit array where each bit represents an ASCII character. Use 1 for the characters you want as break characters. The ability to define your own break tables is optional in older versions of SINTRAN III.
If 8-bit I/O is set (TerminalFunction, function number 112), you will get break always if bit 7 in the break table is set.

Parameters¶

Logical device number. See appendix B. Only used by RT programs. Your own terminal is always selected for background programs.

Break strategy. Negative values gives break on no characters.

Value	Description
0	Break on all characters.
1	Break on control characters, i.e. ASCII values less than 32 and DEL. This is the default.
2	Special break table used by the MAC assembler.
3-6	System defined break strategy.
7	User-defined break table. See the next parameter.
8	Last user-defined break table. (Only meaningful with strategy 7.)
9	Change the maximum numbers of characters before break only.

User-defined break table, i.e. 128 bits which represent the ASCII characters. Use 1 for the characters you want as break characters. See the ASCII table in appendix F.
Maximum number of characters before break. Dummy with break strategies 0, 1, 2.

SetCommandBuffer¶

Transfers a string to the command buffer. The command buffer contains the last command input from the terminal. You may read the command buffer by reading from logical device number 0. See InByte.

The command @TERMINAL-STATISTICS lists the command buffer.
You may apply the SINTRAN III command editing characters to the command buffer when the program has terminated.
The parameter is fetched through the alternative page table.
You may use this monitor call to erase sensitive information in the command buffer, e.g., password parameters.

3B SETECHO¶

When you press a key on the terminal, a character is normally displayed. This is called echo. You modify a terminal's echo with this monitor call.

If 8-bit I/O is set (TerminalFunction, function number 112), you will get echo always if bit 7 in the echo table is set.

PARAMETERS¶

The terminal's logical device number. See appendix B. Only needed for RT programs. Background programs ignore this parameter. The user's terminal is assumed.
Echo strategy. Less than 0: No echo, e.g. for password fields.
- 0: Echo on all characters.
- 1: Echo on all characters except control characters.
- 2: Special echo used by MAC.
- 3-6: System defined echo.
- 7: User-defined echo. See the next parameter.
- 8: Last user-defined echo table. (Only meaningful with echo strategy 7.)
User-defined echo table. Ignored if the echo is different from 7. Use 128 bits to represent the ASCII characters. Use 0 for the character that should have echo. For example, if bit number 65 is 0, the character A gives echo. See the ASCII table in appendix F.

237B SetFileAccess SFACC¶

Sets the access protection for a file. You should specify the access for yourself, friends, and other users. The default file access for yourself is full access. Your friends have read access only. Other users have no access.

You need directory access to a file to change the file access. User SYSTEM and RT may set the access protection for any files.
Use the characters R, W, A, C, D, and N to specify the legal file access. R means Read. W means Write. A means Append to the end of a file. C means Common, i.e. more than one user may access the file at a time. D means Directory access, i.e. the file may be deleted, new versions created, etc. N means No access.
Use @FILE-STATISTICS to check the file access.

See also CreateFriend, SetObjectEntry, @SET-FILE-ACCESS, and @SET-DEFAULT-FILE-ACCESS.

PARAMETERS¶

File name. It is most efficient to use unabbreviated file names, e.g. EXAMPLE:TEXT. The default file type is :SYMB.
Public access. Use N or a combination of R, W, A, C, and D. Public access is typically set to R or N.
Friend access. Use N or a combination of R, W, A, C, and D. Friend access is typically set to RWA or R.
Own access. Use N or a combination of R, W, A, C, and D. Own access is typically RWACD, though lesser combinations can be used (e.g. RWAC to protect your own files from accidental deletion by yourself).
Standard Error Code. See appendix A.

436B SetND500Param¶

Sets information about an ND-500 program. Use GetND500Param to read the 5 parameters when a program is terminated.

SINTRAN III sets some of the parameter values if you give the command @ENABLE-TERMINATION-HANDLING first.

See also TerminationHandling, GetUserParam, SetUserParam, and GetND500Param.

Parameters¶

The five user parameters as an array. SINTRAN III's termination handling returns the following:

Parameter	Description
1	Bit 24:16 contains the user index. Bit 15:0 contains the directory index.
2	Logical device number of the terminal.
3	Fatal error or the monitor call ErrorMessage returns the error number. If ESCAPE was pressed, -1 is returned.
4	Set by SetND500Param.
5	Set by SetND500Param.

The parameters are returned if the user presses the ESCAPE key, if the monitor calls ExitFromProgram or ErrorMessage are executed, or if a fatal error occurs. You can set all parameters if no termination handling is enabled.

SetObjectEntry¶

Changes the description of a file. An object entry describes each file. It contains the file name, the access rights, the date it was last opened for read and write, the size, and more. You may use GetObjectEntry to read an object entry, change parts of it, then write it back with SetObjectEntry.

You specify the directory index, the user index, and the object index.
There is one object entry for each version of a file.
Only user SYSTEM can change the object entry of a file without read or write access to the file.
On the ND-100 you may access files on remote computer systems if the computers are connected through a COSMOS network.

See also GetObjectEntry, GetAllFileIndexes, and @CHANGE-OBJECT-ENTRY.

PARAMETERS¶

The 64 byte object entry. See appendix C.
The directory index. See GetAllFileIndexes.

SetProcessPriority¶

Sets the priority for a process in the ND-500. The priorities vary from 0 to 255. The process with the highest priority is executed first.

The priorities of background programs normally vary between 20 and 64. SINTRAN III modifies the priorities all the time. This is done to allow several jobs to share the CPU. Specify 0 to execute a process in the same way.
With SetProcessPriority, you may fix the priority.

316B SetRemoteAccess¶

Switches remote file access on and off. The COSMOS network allows you to access files in remote computers directly. Use DefaultRemoteSystem or QSET-DEFAULT-REMOTE-SYSTEM to specify a default remote system. If a file does not exist in the local system, the default remote system is searched. SetRemoteAccess switches this function on and off.

You may include a remote system identification in the file name. Only the specified system is searched.
This monitor call is only available with COSMOS.

See also QSET-LOCAL-MODE or QSET-REMOTE-MODE.

SetUserParam¶

Sets information about a background program. Use GetUserParam to read the 5 parameters when a program is terminated.

SINTRAN III sets some of the parameter values if you give the command @ENABLE-TERMINATION-HANDLING first.

See also TerminationHandling, GetUserParam, @DEFINE-TERMINATION-HANDLING, @DISABLE-TERMINATION-HANDLING, and @SET-USER-PARAMETERS.

PARAMETERS¶

The five user parameters. This is an array of 16-bit integers on the ND-100. ND-500 uses an array of 32-bit integers. SINTRAN III's termination handling returns the following:

Parameter	Description
1	The last byte contains the user index. The byte in front of it contains the directory index.
2	Logical device number of the terminal.
3	Fatal error or the monitor call ErrorMessage returns the error number. If ESCAPE was pressed, -1 is returned.
4	Set by SetUserParam.
5	Set by SetUserParam.

The parameters are returned if the user presses the ESCAPE key, if the monitor calls ExitfromProgram or ErrorMessage are executed, or if a fatal error occurs. You can set all parameters if no termination handling is enabled.

103B STARTUPINTERVAL¶

Prepares an RT program for periodic execution. The interval between the executions can be specified in hours, minutes, seconds, and basic time units. A basic time unit is 1/50th of a second.

The RT program is not started. Use StartRTProgram, @RT, or similar, to start it.
StopRTProgram, Disconnect, @ABORT or @DSCNT cancel this monitor call.
One execution may be unfinished when it is time for the next execution, in which case the program's restart flag is set. If the delay becomes as long as two intervals, one execution is lost.
The interval replaces any earlier specified intervals.
AdjustClock and @CLADJ do not affect the interval.

See also ExactInterval and @INTV. ExactInterval allows you to specify intervals between 0 and 4294967647 basic time units.

PARAMETERS¶

Parameter	Description
Address of an RT description. 0 means calling program. GetRtAddress gives RT description addresses.
Number of time units between executions of the program.
The type of time units. 1 = basic time units, i.e. 1/50th of a second, 2 = seconds, 3 = minutes, 4 = hours.

307B TerminalNoWait TNOWAI¶

Switches No Wait on and off. No Wait is useful for input from, and output to, character devices, e.g. terminals. In No Wait, the program does not wait for input or output. Monitor calls like InByte return the error code 3 instead.

SuspendProgram or WaitForRestart may passivate the program afterwards. The program then restarts when the device detects a break.
The input buffer must be emptied before passivating the program.

See also InByte, OutByte, and NoWaitSwitch.

Parameters¶

Parameter	Description
DevNo	Logical device number of a character device. See appendix B.
IOFlag	Input or output flag. Use 0 for input and 1 for output.
NoWaitFlag	No Wait flag. Use 0 to switch No Wait off, and any other number to switch it on.

TimeOut¶

Suspends the execution of your program for a given time. The execution then continues after the monitor call. The restart cause is indicated. Avoid using Time Out from ND-500, use ND500TimeOut instead.

No reserved files or devices are released.
The execution continues immediately if the program has its restart flag set.
You may use NoWaitSwitch. Then the program restarts when a break occurs.
If a program has been rescheduled by the monitor call SET (mon 101, DelayStart) or ABSET (mon 102, StartupTime), this rescheduling will be destroyed when you use TimeOut.

See also SuspendProgram, WaitforRestart, and ND500TimeOut.

PARAMETERS¶

Number of time units to suspend the program.
The type of time units. 1 = basic time units, i.e. 1/50th of a second, 2 = seconds, 3 = minutes, 4 = hours.
Restart cause. 0 means that the defined time has elapsed. 1 means that a break restarted the program. -1 means that the RT program was scheduled for repeated execution.

335B TRANSFERDATA¶

Transfers data between physical memory and a mass-storage device, e.g. a disk. You may perform various device control functions. This monitor call is mainly used by the operating system itself.

The program must run on ring 2. You may use any page table. Both demand and non-demand segments are legal. Memory areas for DMA transfer must be fixed contiguously.
For calls to magnetic tape or other devices where the last parameter contains number of bytes/words read or other return parameters, the parameter list must be in resident memory, i.e. an area with fixed page-table contents.
The physical memory area must be contiguous. Older versions of magnetic tapes or disk controllers cannot cross physical memory-bank boundaries of 128 Kbytes. These magnetic tapes have ND numbers less than ND-537. The disks have ND numbers less than ND-559.
Only two programs may execute TransferData at a time.

See also DataTransfer, ReadFromFile, and WriteToFile.

PARAMETERS¶

→ Logical device number. See appendix B.
→ Function code. See the tables on the following pages.
→ Physical memory address.
→ Block address on the disk. See the tables on the following pages.
→ Number of blocks to transfer.
← Error code. Negative, if error. Contains a hardware status.

CALL FORMATS¶

The call formats are marked from a-i. All formats give status on return. See appendix A. The return status >=0 means the call terminated correctly. Parameters which do not affect the call format are called "dummy" below. All call formats contain logical unit number (0-3) in function code bits 6-8.

The call format "a" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, dummy)

The hardware status is returned as error code. The device must be reserved. Otherwise a positive error code may not be the correct hardware status.

The call format "b" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, dummy)

Status is Standard Error Code.

The call format "c" is:¶

Status=EXABS(logical device number, Unit/function code, physical memory address, sector address, no of sectors to read)

The call format "d" is:¶

Status=EXABS(logical device number, Unit/function code, physical memory address, sector address, no of sectors to write)

The call format "e" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, floppy format number)

The call format "f" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, sector address)

The call format "g" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, destination unit number)

The call format "h" is:¶

Status=EXABS(logical device number, Unit/function code, dummy, dummy, first sector address of track)

Page 549¶

SINTRAN III Monitor Calls¶

The call format "i" is:¶

Status=EXABS(logical device number,Unit/function code,physical memory address,dummy,dummy)

Format code is returned in physical memory address.

The call format "j" is:¶

Status=EXABS(logical device number,Unit/function code,physical memory address,dummy,dummy)

Disk layout table (8 words) is returned in physical memory address.

UserDef0..UserDef7¶

User-defined monitor call. You can implement up to 8 monitor calls yourself. These are named UserDef0, UserDef1,... UserDef7. The short names are US0, US1,...US7. To do this you need good knowledge of SINTRAN III. See the SINTRAN III listing parts one and two.

Use the DMAC subsystem or the @LOOK-AT command to patch in the MAC instructions of your monitor call. Place the code in physical memory after the SINTRAN III symbol 7ENDC. You ought to do this from a mode file. The monitor call is lost in a warm start.
Use the SINTRAN-SERVICE-PROGRAM command DEFINE-USER-MONITOR-CALL to define the entry point of the monitor call.
There are other ways of implementing user-defined monitor calls.
Some monitor calls are no longer in use. You may use these for user-defined monitor calls.
If the subsystems TPS is installed, the user-defined monitor calls 170 to 175 may not be used.

PARAMETERS¶

Both input and output parameters are user defined. You are advised to transfer parameters in the same way as SuspendProgram, InString, WriteToFile, etc.

64B WarningMessage¶

Outputs a file system error message. Appendix A shows the messages connected to each error code. The error code is input. The program continues.

The error message is output to the terminal. In batch jobs, mode jobs, and RT programs it is output to the error device. The error device is normally the console.
Error code 0 is illegal.

See also GetErrorMessage and ErrorMessage. ErrorMessage writes out the error message and terminates the program.

Parameters¶

→ Error code of the message to be printed. Use octal numbers.

6B WRITESCRATCHFILE¶

Writes randomly to the scratch file. One block is transferred. There is one scratch file connected to each terminal. It is opened for random read and write access when you log in. Its file number is 100B.

The standard block size is 512 bytes. You can change this with SetBlockSize. The first block is number 0.

See also WriteBlock, WriteToFile, and ReadScratchFile.

12OB WriteToFile¶

Writes any number of bytes to a file. The read operation must start at the beginning of a block. The file must be opened for random write access.

The standard block size is 512 bytes. You can change this with SetBlockSize. The first block is number 0.
You may use access code D for direct transfer. Then the block size must be a multiple of the page size. The number of bytes to transfer must be a multiple of the block size. The data must be fixed contiguously in memory.
Peripheral files are always written to sequentially.
Data transfer across segment or RT common limits is illegal as this would be likely to result in inconsistent data.

See also SetStartBlock, SetBlockSize, WriteDiskPage, WriteBlock, and ReadFromFile.

PARAMETERS¶

File number. See OpenFile.
Wait flag. Use 0 to suspend the program until the transfer is completed. Other values make the program continue. You may check that the transfer is completed by AwaitfileTransfer. Background programs must always wait until data is transferred.
Data to be transferred.
Block number to start writing from. Use -1 to write to the next block.
Number of bytes to be written.
Standard Error Code. See appendix A.

APPENDIX A: ERROR MESSAGES¶

This appendix lists the SINTRAN III error messages. Errors from RT programs are output in the form shown here:

23.59.57 ERROR 14 IN BAK07 AT 114721; OUTSIDE SEGMENT BOUNDS

This means that error number 14 occurred at 23:59.57 o'clock. The RT program BAK07 came into the error situation when executing memory address 114721. Note that the error numbers reported from RT programs are decimal numbers.

Some error messages output additional information. In most cases, an RT program entering an error situation is aborted, whereas background programs are not aborted. Error messages from background programs are displayed as texts only, e.g. NO SUCH FILE. The message is displayed on the terminal if the error relates to an interactive program. Other messages are written to the error device.

The following table lists the error numbers/messages which may be reported from RT programs.

APPENDIX I: ND TERMINAL TYPES¶

This list shows the current types defined by Norsk Data A.S. New numbers are allocated as ND adds new terminal types to systems.

The terminal type number is calculated as follows:

Bit	Description
15	Reserved.
14	Set to one if the terminal is a VDU (not hard copy).
13	Set to one if the terminal handles the ASCII backspace character (BS) properly.
12	Set to one if ASCII form feed (FF) gives new page or clear screen.
11	Set to one if the VDU has cursor positioning (either directly or by use of cursor arrows).
10	Set if the terminal utilises ASCII escape (ESC) within input sequences.
9-8	Not used.
7-0	Terminal model number. See the following pages.

Example:
The number for TANDBERG TDV-2115 on logical device number 49 is set as follows:

@SET-TERMINAL-TYPE 49,164003B

or more permanently

@SINTRAN-SERVICE-PROGRAM  
*CHANGE-DATAFIELD \<terminal number> INPUT YES YES YES  
CTTYP/164003  
.  
EXIT

SINTRAN III Monitor Calls¶

APPENDIX K: GLOSSARY¶

This glossary explains the SINTRAN III terms in the manual. Some general terms are included. The explanations are intended for programmers.

Access code¶

A number describing how a file is accessed. For example, 0 means it is written to sequentially.

ADA¶

A high level programming language. Available on ND-500(0).

Address area¶

The maximum amount of memory a program may use. The address area on ND-100 is 128 Kbytes for one-bank programs and 256 Kbytes for two-bank programs. ND-500(0) has no practical restrictions on the address area.

Allocated file¶

A contiguous file created at a particular page address on the disk. See Createfile.

ASCII¶

A code where each character is assigned a number. For example, "A" is represented by 65, "B" is represented by 66, etc. The ASCII code includes control characters. Appendix F contains an ASCII table.

ASSEMBLY-500¶

The ND-500(0) assembly language.

B¶

Number followed by a "B", eg., 400B, means octal numbers.

Background program¶

A program that is loaded with the BRF-LINKER, NRL, or the LOAD command in a compiler. Programs are either background programs or RT programs.

BACKUP-SYSTEM¶

A SINTRAN III system used to copy several files efficiently, eg., to make security copies. See the SINTRAN III Utilities Manual (ND-860151).

BAK01¶

RT programs called BAK01, BAK02, BAK77, BK100, etc., control each terminal. The RT programs are a part of SINTRAN III.

Basic time unit¶

One 1/50 of a second. The length can be changed by the System Supervisor.

Batch¶

A way of executing command and background programs independently of any terminal. Input is read from a mass storage file instead of a terminal.

BK100¶

RT programs called BAK01, BAK02, BAK77, BK100, etc., control each terminal. The RT programs are a part of SINTRAN III.

Block¶

A file is logically divided into blocks. A block is normally 512 bytes. Some monitor calls operate on blocks instead of bytes. The first block of a file is number 0.

Page 648¶

SINTRAN III Monitor Calls Glossary¶

BPI¶

Bits stored per inch.

BRF-LINKER¶

A SINTRAN III subsystem to load and link programs.

Buffer¶

A buffer is a temporary storage area.

Byte¶

A byte is always 8 bit in ND computer systems.

CAMAC¶

A common interface between a computer and peripheral equipment.

Capability¶

A domain keeps a description of each logical segment in use. The description is called a capability. It contains information about access rights, location in physical segments, and sharing with other processes. See the manual ND-500(0) Loader/Monitor (ND-860136).

Character device¶

A device which receives and sends one byte at a time, eg., a terminal, a printer, or a magnetic tape station.

COBOL¶

A high level programming language. Available on ND-100 and ND-500(0).

Compiler¶

SINTRAN III subsystems to translate high level language programs to code that can be loaded and then executed. The compilers for ND-100 have names like FORTRAN-100, PASCAL-100, etc. The ND-500(0) compilers have names like FORTRAN-500 and COBOL-500.

Console¶

A terminal which prints on paper instead of a video display unit. Most computers have a console used for system supervising. The console is normally also the error device.

Contiguous file¶

A file with fixed length. Its pages are placed contiguously on the disk. The access to contiguous files is faster than to ordinary files. See CreateFile.

Control character¶

A control character, eg., CTRL A, is given by holding down the CTRL key on the terminal keyboard while pressing A. Control characters are mostly used to perform certain functions, eg., delete a character. Control characters have ASCII codes in the range 0:37B.

COSMOS¶

Norsk Data's family of computer network products.

Database¶

A system used to store and retrieve information in an efficient way. The SINTRAN III subsystem SIBAS is the most common database system on ND computers.

Default¶

A value that is assumed if nothing is specified. For example, the default file type :DATA means that this file type is assumed if you do not specify the file type in a file name parameter.

Demand segment¶

The pages of a segment are normally moved from the disk to physical memory one by one when they are accessed. Demand segments allow this. Non-demand segments are moved as a whole. This gives faster access. The RT LOADER defines segments as demand or non-demand. See the SINTRAN III Real Time Guide (ND-860133).

Page 649¶

SINTRAN III Monitor Calls¶

Glossary¶

Device¶

In most cases equipment connected to the computer, e.g., terminals, printers, links to other computers, and disks. Various types of internal devices exist in addition, e.g., semaphores and buffers. Opened files are treated as devices. Most monitor calls identify devices by their logical device number. See appendix B.

Direct task¶

Programs run as an extension to the operating system. Direct tasks normally handle devices which require fast response.

Directory¶

For most practical purposes, you can regard directories as groups of files. There is normally one directory for each disk or floppy disk. A file, for example, (PACK-ONE:JOHN)TEST:TEXT1, belongs to the directory called PACK-ONE.

DMA¶

Direct memory access. Data is transferred between a device, e.g., a disk, and memory one page at a time.

Domain¶

ND-500(0) programs are called domains. The address space of a domain is divided into segments. For example, one segment may contain the main program, and another a routine library. The routine library can be shared with another domain.

Echo¶

When you press a key on the terminal, a character is normally displayed. This is called echo. You may turn echo on and off. It is also possible to specify that only some characters should give echo.

End-of-file¶

An ASCII character which marks the end of a file. Abbreviated EOF.

ErrCode¶

A system defined variable in some programming languages. You can test the ErrCode to see if errors have occurred in a monitor call. If it is greater than 0 something is wrong. Appendix A describes the various ErrCodes.

Error code¶

Some monitor calls return an error code. If it is greater than 0, an error has occurred. In some programming languages, the error code is available in the system variable ErrCode. In MAC, it is returned in the A register. ASSEMBLY-500 returns the error code in the W1 register. Appendix A shows the meaning of error codes.

Error device¶

A terminal used for error messages from RT programs and SINTRAN III itself. The error device is normally the console. This can be changed by the System Supervisor.

Escape function¶

The ESCAPE key on the terminal normally terminates a program. This is called user break. You can turn this escape function off with DisableEscape. EnableEscape turns it on again.

Execution queue¶

The RT programs waiting for the CPU. See the SINTRAN III Real Time Guide (ND-860133). The command @LIST-EXECUTION-QUEUE lists the contents of the queue.

Exception¶

Some programming languages have user defined exception handling. A program may execute a set of statements, called an exception handler, when special errors conditions occur. For example, monitor calls with illegal parameters may cause an exception.

Page 650¶

SINTRAN III Monitor Calls Glossary¶

File name¶

(PACK-ONE:FLOPPY-USER)EXAMPLE-FILE:TEXT1 is an example of a complete file name in SINTRAN III. PACK-ONE is the directory name. FLOPPY-USER is the owner of the file. The file name is EXAMPLE-FILE. The file type is TEXT. The file version is 1. There are default values for most parts of the complete file name.

You may access files in remote computers when the COSMOS network is installed. The complete file name must then be preceded by an identification of the remote system. A user on the remote system must be specified, e.g., SNRURE(PACK-ONE:OLE(ABC:XYZ)).. SNRURE is the name of the computer. User OLE on the main directory PACK-ONE has password ABC and project password XYZ. You get the access rights of user OLE. There are default values for most parts of the remote system identification.

File number¶

A number given to a file when it is opened. The file number is used to identify the file in read and write operations. File numbers are a special kind of logical device numbers.

Fix¶

The pages of a program's address area are normally swapped between physical memory and the disk during execution. You can fix pages in physical memory. See FixScattered, FixContiguous, and similar monitor calls.

Flag¶

A parameter which may have two different values, e.g., on or off. In a few cases, flags have been allowed to have three values.

FORTRAN¶

A high level programming language. Available on ND-100 and ND-500(0).

Friend¶

A user with special access privileges to your files. You may create up to 8 friends. Use the command @CREATE-FRIEND.

HDLC¶

A device which connects two computers in a network. One HDLC is installed in each computer. A cable connects them.

Indexed file¶

SINTRAN III's most common type of file. The size of the file adapts to what is written to it. Its pages are scattered around on the disk. The first page contains pointers to these pages. See CreateFile.

Internal device¶

Normally a character buffer or a semaphore.

Internal time¶

The time since SINTRAN III was started. It is specified in basic time units. There are 50 basic time units in a second.

Interrupt¶

A device sends an interrupt when it needs attention from the CPU. For example, an interrupt is sent when you press a key on the terminal. The ND-100 has 16 levels of interrupt. Each device is connected to one of these levels. The higher levels are handled first.

I/O wait¶

A waiting state where a program waits for input or output.

Page 651¶

SINTRAN III Monitor Calls¶

Glossary¶

LAMU. Logically addressed memory unit. SINTRAN III's LAMU system is an extension to the segments. It makes it possible for background and RT programs to access a larger address area than available by the three segments. The address space of a LAMU may be shared by several CPUs.

Library. A set of compiled routines. Your program may call these routines if you load the library together with your program. The high level language interface to the monitor calls is provided as a library.

Local function. You can log in on remote computers if the COSMOS network is installed. Normally, a key on your terminal terminates this connection. DisableLocal turns this local function off. EnableLocal turns it on again.

Local system. The computer you are physically connected to in a data network. Opposed to remote systems.

Log in. You must log in before you can start working on a terminal. Press the ESCAPE key and enter your user name and your password. A project password is sometimes needed in addition.

Logical device number. A number that identifies a device. Opened files are given logical device numbers from 100-177. You may use logical device number 1 to access your own terminal from background programs. See appendix B.

Logical segment number. A domain in ND-500(0) numbers its segments from 0:31. These logical segment numbers are different from the physical segment numbers.

MAC. The ND-100 assembly language.

Mode job. Commands are read from a mass storage file instead of the terminal. Output is to a terminal. Mode jobs are used to execute commonly used sequences of commands in an efficient manner.

Monitor call. Programs request services from the operating system through monitor calls. Monitor calls look like routine calls. For example, a program may read the current time or write to a file by using monitor calls.

Monitor call number. Each monitor call has a number. This number is written in the headings of the reference chapter. The trailing B, eg., 256B, means that it is an octal number.

ND-100. ND's 16-bits computer. ND Satelites and ND Compacts are ND-100 computers. ND-500(0) computers has a built-in ND-100 computer.

ND-500(0). ND's 32-bit computer. An ND-500(0) has both an ND-100 and an ND-500(0) CPU. Various models like ND-530, ND-570, etc., exist.

ND-500(0)-MONITOR. An extension of SINTRAN III for ND-500(0) computers. It is run as a subsystem under SINTRAN III. ND-500(0)-MONITOR provides almost the same set of monitor calls on the ND-500(0) as available on the ND-100.

Page 652¶

SINTRAN III Monitor Calls Glossary¶

No wait¶

A program normally waits until input and output are completed. The monitor call NoWaitSwitch will cause the program to continue in parallel with the input or output operation.

Object entry¶

An object entry describes each file. The command @FILE-STATISTICS outputs parts of this information. See the file system description in the SINTRAN III System Supervisor (ND-830003).

Object index¶

Identification of an object entry.

Octal number¶

In the octal number system you count 1, 2, 3 ... 6, 7, 10, 11, 12 ... 17, 20, 21 ... 27, 30 ... 77, 100 ... 177, 200 etc. The digits 8 and 9 do not exist. Octal numbers are written with a trailing B, eg., 648B. The V command in PED and NOTIS-WP converts to and from octal numbers. Our ordinary number system is called decimal.

Page¶

A page is 2048 bytes of physical memory or disk space.

Page table¶

SINTRAN III has 4 page tables. They are numbered 0–3. Each page table allows you to access 128 Kbyte memory. You may use more than one page table. Use AltPageTable to switch.

Parity¶

SINTRAN III uses even parity on ASCII characters. That is, the ASCII characters use bit 6–0 in a byte. The 7th bit is the parity bit. It is set if there is an odd number of bits set in bit 6–0.

For example, carriage return has the ASCII value 13. When input from a terminal, your program receives 141 because the parity bit is set. Subtract 128 to get the ASCII value, i.e., 141 - 128 = 13. Note that the bit pattern for 13 is 00001101, i.e., 3 bits are set. This causes the parity bit to be set. The value 10001101 is returned.

Pascal¶

A high-level programming language. Available on both ND-100 and ND-500(0).

Project password¶

An additional password used by the accounting system. It is requested when you log in. Normally, all users working on a common project have the same project password.

Patch¶

Alter or extend the machine instructions of the operating system or possibly a subsystem. This is normally done with the command @LOOK-AT or the DMAC subsystem.

Periodic program¶

An RT program that is started automatically at regular intervals. See the monitor call StartupInterval.

Peripheral device¶

Equipment connected to the computer, eg., printers, floppy disk drives, and terminals.

Peripheral files¶

Peripheral equipment, eg., terminals, printers and floppy disk drives, are handled as files for input and output. See SetPeripheralFile.

Page 653¶

SINTRAN III Monitor Calls¶

Glossary¶

Permanently opened file. Files may be set permanently open by the monitor call SetPermantOpen. Closefile with -1 as parameter will not close such files.

PIOC. A programmable input and output processor. Commonly used in data communication. See the manual PIOC Software Guide (ND-860161).

PLANC. A high-level programming language particularly for ND computers. Available on ND-100 and ND-500(0).

Physical device number. Each device is identified by a physical device number. It is used in the IOX instruction when accessing the device.

Physical memory. The main memory of a computer. A memory management system allows ND-100 programs to address 128 pages of virtual memory. The virtual memory pages are swapped into physical memory when accessed.

Process. A program in the ND-500(0) is called a process.

Protection ring. The ring determines which machine instructions a program may execute. Each segment belongs to one of four rings. The rings are numbered from 0 to 3. Background programs use ring 0. See the SINTRAN III Real Time Guide (ND-860133).

Random access. When you read or write to specified addresses in a file. The opposite is sequential access where you access the bytes one by one from the start.

Reentrant program. A program that may be used by several users at a time. Reentrant programs are placed on a segment, not on a file. This saves time and space.

Reentrant segment. An ND-100 segment with a reentrant program. Use the command @DUMP-REENTRANT or the RT-LOADER to place a program on a reentrant segment.

Reference. Documentation intended to look up particular details. Prerequisite knowledge of the matter is needed.

Remote system. A computer installation accessed via a data network. Opposed to your local system.

Resource. In this documentation, a resource is either a device or an opened file.

Restart flag. Each RT description has a restart flag. If set, the program restarts immediately when it terminates.

Resident memory. An area in physical memory used by the most important parts of SINTRAN III. The pages in this area are never swapped out to the disk.

Page 654¶

SINTRAN III Monitor Calls Glossary¶

Ring¶

The ring determines which machine instructions a program may execute. Each segment belongs to one of four rings. The rings are numbered from 0 to 3. Background programs use ring 0. See the SINTRAN III Real Time Guide (ND-860133).

RT&Common¶

An area in physical memory where Real Time programs may exchange data.

RT Description¶

A block of information about each RT program. Each RT description is identified by an address in a table of all RT programs. GetRTAddress or @LIST-RT-PROGRAMS gives the address. Further information is found in the SINTRAN III Real Time Guide (ND-860133).

RT LOADER¶

A loader needed to load RT programs on the ND-100. See the manual SINTRAN III Real Time LOADER (ND-860051).

RT Program¶

Real time program. RT programs may use monitor calls not available to background programs. All RT programs must be loaded with the RT-LOADER, not the BRF-LINKER. User RT owns the RT programs. See the SINTRAN III Real Time Guide (ND-860133).

Scratch File¶

A scratch file is connected to each terminal. It is opened automatically when you log in. Some subsystems, e.g., PED, use the scratch file. You may also use it for temporary storage of information. It has file number 100. User SCRATCH owns the scratch files. The scratch file is normally reduced to 32 pages when you log out.

Segment¶

An address area where programs are placed before execution. Segments are areas on the disk. During execution pages are swapped in and out of main memory. The SINTRAN III Real Time Guide (ND-860133) describes segments on the ND-100. Segments on the ND-500(0) differ from the ND-100. See the ND-500(0) Loader.

Semaphore¶

A device used to synchronize RT programs. For example, the semaphore allows you to control that only one program accesses a device at a time.

Sequential Access¶

When you read from or write to a file byte by byte from the beginning to the end. The opposite is random access.

Short Name¶

Each monitor call has a short name. For example, the short name of ExactInterval is DIntv. This is an old name. It is kept for backward compatibility.

SIBAS¶

The database system on ND computers.

SINTRAN III¶

The operating system on ND computers. It provides services through commands and monitor calls.

SINTRAN-SERVICE-PROGRAM¶

A program the System Supervisor uses to make changes in SINTRAN III. See the manual SINTRAN III System Supervisor (ND-830003).

Page 655¶

SINTRAN III Monitor Calls¶

Glossary¶

Skip return¶

Skip return from a monitor call means that the first instruction following the monitor call is ignored. MAC uses skip return if no standard error code is returned.

Spooling¶

A system to queue files you want to print when the printer is occupied.

Standard error code¶

Some monitor calls return an error code. If it is greater than 0, an error has occurred. In some programming languages, the error code is available in the system variable ErrCode. In MAC it is returned in the A register. ASSEMBLY-500 returns error codes in the W1 register. Appendix A shows the meaning of error codes.

Swap file¶

The pages of a segment in the ND-500(0) are swapped between physical memory and the disk. The segment is copied to a swap file if you do not want to modify the original contents of the segment. There is one or more swap files in each ND-500(0) system.

TAD¶

Terminal access device. Used by COSMOS when you log in on a remote computer.

Temporary file¶

The contents of a temporary file is deleted the first time the file is read. Use the monitor call SetTemporaryFile to make a file temporary.

Terminal¶

In this manual, a terminal means a video display unit and a keyboard unless otherwise specified.

Terminal type¶

A number identifying each type of terminal. See appendix H.

Timeout¶

A timeout may be specified in various waiting situations. This will be the maximum waiting time.

Time queue¶

The RT programs which are set to start at a particular time. @LIST-TIME-QUEUE lists the contents of the queue. Further information in the SINTRAN III Real Time Guide (ND-860133).

Time slicer¶

The time slicer allows programs to share the CPU. Each program executes for a short interval. Uncompleted programs return to the execution queue.

Trap handling¶

Detected error conditions, such as division by 0, or protect violation, cause a hardware trap in the ND-500(0). Either a standard trap handler or a user defined set of statements may be executed.

User name¶

In SINTRAN III, every user has a user name, eg., P-HANSEN. Up to 256 users may be defined in each directory. They have user indexes from 0 to 255. The monitor call ExecutionInfo returns the user index if needed in a program.

User break¶

A background program is terminated when the user presses the ESCAPE key. This is called user break. Use DisableEscape to inhibit user break.

Page 656¶

SINTRAN III Monitor Calls¶

Glossary¶

User Environment. A subsystem which makes the operating system more user friendly. It is mainly intended for office automation users.

User RT. A privileged user with access to real time facilities. User RT owns all RT programs. See the SINTRAN III Real Time Guide (ND-860133).

User SYSTEM. The user name of the System Supervisor. User SYSTEM may use all commands and monitor calls.

Virtual memory. The address space available to programs. The memory management system automatically swaps pages into physical memory when your program accesses them.

Volume. A set of files on a magnetic tape or floppy disk. A volume has a function similar to a directory. Files in a volume can only be accessed sequentially. See the BACKUP-SYSTEM description in the SINTRAN III Utilities Manual (ND-860151).

Transducers and Sensors¶

Introduction¶

Transducers convert one form of energy into another. In the context of sensors:

Input transducers convert physical quantities to electrical signals.
Output transducers convert electrical signals to physical quantities.

Types of Transducers¶

Type	Conversion	Example
Electromechanical	Mechanical to Electrical	Microphone
Electro-optical	Optical to Electrical	Photodiode
Electromagnetic	Magnetic Field to Electrical	Hall Effect Sensor

Applications¶

Applications of these devices range from industrial to consumer electronics, with varied utilizations like sound level measurement in microphones and light detection in photodiodes.

Conclusion¶

The understanding of transducers and sensors is crucial for designing systems that interaction with the physical environment.
