ND-Pascal. Version J.¶

With this release of ND-Pascal a new revision of the user manual, ND-60.124.5, has been produced. The manual covers both ND-100 Pascal and ND-500 Pascal.

Corrected errors¶

All known errors in version I have been corrected. Some of these were of a minor nature, and are not reported below.

ND-500: Character assignment failed when option C+ was in effect.
ND-100: In some cases the compiler generated erroneous code re-using already occupied stack space.
The maximum legal length of a source code line is now 96 characters both for the ND-100 and ND-500 compilers.
ND-500: FILE OF REAL did not work correctly.
A program would hang at program end when the same file was CONNECTed several times without intervening DISCONNECTs.
The call PAGE; did not work correctly.

Revision Notes¶

ND-500: The compiler in some cases generated erroneous code for Boolean expressions.
An error in the CONNECT procedure which occurred when CONNECTing a logical unit has been corrected.
ND-100: A problem with )LIB marks when generating overlay modules has been corrected.
The procedure CONNECT's buffer holding the SINTRAN file name has been extended to 60 characters.
ND-500: A program initially gave EOLN = TRUE even though the program call had parameters.
ND-500: Byte (character) comparisons erroneously were signed.
An error in the "make set range" run-time routine has been corrected.
Both the values 15 octal and 215 octal will give EOLN = TRUE when option C+ is in effect.
It was not possible to transfer a conformant array parameter to a non-Pascal routine.
ND-100: The interface to PLANC-routines with or without INITSTACK now works correctly. The PLANC-routine has to be defined as STANDARD in the Pascal program.

Extensions and Changes¶

The compilers now accept hexadecimal integer constants. The syntax is:

<hex constant> ::= <sign> <digit> ⊗ <hexdigit> å <size> "H"
<sign> ::= <empty> ⊗ "+" ⊗ "-"
<hexdigit> ::= <digit> ⊗ "A" ⊗ "B" ⊗ "C" ⊗ "D" ⊗ "E" ⊗ "F"
<size> ::= <empty> ⊗ "L"

2. ND-100¶

The stack format of a Pascal procedure or function object has been changed to conform with the standard for PLANC and other ND-100 languages. An object now has six system locations in the header instead of three, as follows:

return address
dynamic link
not used
not used
static link
not used

Note: This change makes it necessary to modify all assembly routines called from a Pascal program. The function value, or first parameter, will now be at relative location 6 to (A)+(B), instead of previously at relative location 3.

3. ND-100¶

The compiler will now produce two-bank BRF code when option B2 is in effect. The new library, PASCAL-2LIB:BRF, must be loaded to produce an executable two-bank program.

It is still possible to make two-bank programs as it was done previously, i.e. by entering the loader command DEFINE NOBKS 2 and loading PASCAL-LIB, but the new method saves space in the instruction bank.

When loading two-bank code to create a system of overlaid modules, one must enter the NRL command:

SET-MODE DATA

before the first OVERLAY-GENERATION command.

Refer to the new ND-Pascal Reference Manual for further details on two-bank programs.
