2. Commit listings and updated compiler source from running PASCAL.PATCHES.card under Mark XV system software. See README.txt for details. 3. Minor change to HMMS2.TEST.card and .lst to reflect symmetry in the chimney temperature profile.

PASCAL Compiler for the Burroughs B5500/B5700
|
|
|
|
A compiler and run-time system for Niklaus Wirth's Pascal language,
|
|
written by Dag F. Langmyhr at Heriot-Watt University in Edinburgh,
|
|
Scotland, ca. 1975.
|
|
|
|
Rather than compiling Pascal source to B5500 object code, this compiler
|
|
translates the Pascal source to Burroughs Compatible Algol (XAlgol). The
|
|
PASCRUN/DISK file is an XAlgol source that is inserted into the XAlgol
|
|
generated from the Pascal source to provide a run-time system --
|
|
actually it is more like a shim between Pascal and standard XAlgol
|
|
intrinsics and I/O.
|
|
|
|
The compiler, run-time system, and patches were originally transcribed
|
|
by Rich Cornwell of North Carolina, US. Proofing and correction were
|
|
performed by Paul Kimpel of San Diego, California, US.
|
|
|
|
HMSS2.TEST.card
|
|
Card deck to compile and run a sample Pascal program. This program
|
|
computes the temperature profile in a square chimney with one side
|
|
against a perfectly-insulated wall and the other three sides exposed
|
|
to ambient air. Note that this program takes almost nine minutes to
|
|
run in the retro-B5500 emulator (which is close to the performance
|
|
of a real B5500).
|
|
|
|
HMSS2.TEST.lst
|
|
Listing produced by running the HMSS2.TEST.card job, including the
|
|
Pascal compiler listing, a listing of the generated XAlgol code, and
|
|
the output from running the generated program.
|
|
|
|
PASCAL.MKXIII.card
|
|
Compile deck and patches to allow SYMBOL.PASCAL.alg_m to compile
|
|
using the B5500 Mark XIII XAlgol compiler.
|
|
|
|
PASCAL.MKXIII-Compile.lst
|
|
Listing produced by running the PASCAL.MARKXIII.card job.
|
|
|
|
PASCAL.MKXV-Compile.lst
|
|
Listing produced by compiling unpatched SYMBOL.PASCAL.alg_m with the
|
|
Mark XV XAlgol compiler.
|
|
|
|
PASCRUN.DISK.alg_m
|
|
XAlgol source for the run-time system inserted into the translated
|
|
XAlgol by the compiler. Transcribed from
|
|
http://bitsavers.org/pdf/burroughs/B5000_5500_5700/listing/
|
|
B5700_Pascal_Apr78.pdf.
|
|
|
|
PATCHES.PASCAL.card
|
|
Card deck containing patches to the Pascal compiler in PATCH/MERGE
|
|
format. Transcribed from the listing in the front of
|
|
http://bitsavers.org/pdf/burroughs/B5000_5500_5700/listing/
|
|
B5700_Pascal_Mar79.pdf.
|
|
**NOTE** This series of patches uses compiler features, primarily $-
|
|
cards, that were implemented after Mark XIII. It works under Mark
|
|
XV, but will not work under Mark XIII software without some
|
|
modifications.
|
|
|
|
PATCHES.PASCAL.MKXV-Compile.lst
|
|
PATCH/MERGE output and XAlgol listing produced by running
|
|
PATCHES.PASCAL.card under Mark XV system software. This run
|
|
generated the updated symbol file SYMNEW.PASCAL.alg_m.
|
|
|
|
SYMBOL.PASCAL.alg_m
|
|
Source for the Pascal compiler/translator, written in Burroughs
|
|
XAlgol for the B5500. Transcribed from
|
|
http://bitsavers.org/pdf/burroughs/B5000_5500_5700/listing/
|
|
B5700_Pascal_Mar79.pdf.
|
|
|
|
SYMNEW.PASCAL.alg_m
|
|
Updated XAlgol source for the Pascal compiler/translator, produced
|
|
by applying the patches in PATCHES.PASCAL.card to
|
|
SYMBOL.PASCAL.alg_m.
|
|
**PLEASE NOTE**
|
|
1. This source was generated using Mark XV system software. The
|
|
source uses XAlgol constructs that are not available in the
|
|
Mark XIII compiler.
|
|
2. Use of this compiler requires changes to the PASCRUN/DISK
|
|
run-time system. AT PRESENT WE DO NOT HAVE THOSE CHANGES.
|
|
This file and PATCHES.PASCAL.MKXV-Compile.lst are provided
|
|
mainly for historical interest; at this point you probably
|
|
do not want to try to use them.
