1. Apply typographical corrections to the source from APL/L200013 on the 1972 CUBEA13 library tape. 2. Add APLPTCH.19710305.alg_m patch file with differences between the APL-IMAGE.alg_m listing and APL/L200013. 3. Add APLPTCH.L200014 patch file from the CUBEA13 tape with changes to APL/L200013. 4. Update provenance and transcription details in README.txt.

APL\B5500
|
|
|
|
APL interpreter for the Burroughs B5500, written by Gary Kildall (of
|
|
CP/M fame), Leroy Smith, Sally Swedine, and Mary Zosel at the University
|
|
of Washington (Seattle, Washington US) in the early 1970s. This version
|
|
was modified by Jose Hernandez of Burroughs Corporation for operation
|
|
under the standard Burroughs Timesharing MCP (TSSMCP).
|
|
|
|
APL-IMAGE.alg_m
|
|
The source of the APL interpreter, written in Burroughs B5500
|
|
Extended Algol, dated "1-11-71" (1971-01-11) in the source. This was
|
|
transcribed from a photocopy of a listing sent to Paul Kimpel by Ed
|
|
Vandergriff of Chaska, Minnesota US. According to Ed:
|
|
|
|
"Originally this came from a long-ago colleague, George P.
|
|
Williams (then of Huntsville, AL [Alabama US]) who shared my
|
|
interests in computer architecture and language implementation;
|
|
if I recall correctly he encountered it as a student at Georgia
|
|
Tech."
|
|
|
|
A scan of that listing is available from:
|
|
http://bitsavers.trailing-edge.com/pdf/georgiaTech/APL-B5500-Listing
|
|
-19710111.pdf
|
|
|
|
Transcription was performed jointly by Hans Pufal of Angouleme,
|
|
France and Fausto Saporito of Naples, Italy during August-September
|
|
2013. Proofreading, corrections, and application of original
|
|
sequence numbers (the last digits of which are often obscured on the
|
|
listing) was done in late 2016 by Richard Cornwell of Durham, North
|
|
Carolina US.
|
|
|
|
In May 2018, three CUBE (Burroughs user organization) Library tapes
|
|
were successfully read by the Computer History Museum in Mountain
|
|
View, California US, and made available to a few B5500 enthusiasts.
|
|
On the CUBEA13 tape is the file APL/L200013 (creation date
|
|
1971-03-08), which appears to be a slightly later version of the
|
|
program, dated 1971-03-05 in the source. Paul Kimpel of San Diego,
|
|
California US used this machine-readable version to correct left-
|
|
margin indentation, last digits of sequence numbers, and numerous
|
|
typographical errors that had escaped detection during proofreading.
|
|
|
|
APL-IMAGE-List.lst
|
|
Compilation listing of APL-IMAGE.alg_m. This was compiled using Mark
|
|
XIII Algol using the following deck:
|
|
|
|
?COMPILE 0APL/DISK ALGOL LIBRARY
|
|
?ALGOL STACK=1000
|
|
?ALGOL FILE NEWTAPE=NEWSYM/APL SERIAL
|
|
?DATA CARD
|
|
$CARD LIST SINGLE NEW
|
|
<source images from APL-IMAGE.alg_m
|
|
?END
|
|
|
|
The "0APL" MFID is necessary in order to be able to execute the
|
|
codefile under CANDE as APL/DISK.
|
|
|
|
APLPTCH.19710305.alg_m
|
|
A patch deck containing the few differences between the 1971-01-11
|
|
version of the source archived here and the 1971-03-05 version on
|
|
the CUBEA13 library tape.
|
|
|
|
APLPTCH.L200014.alg_m
|
|
A patch deck for the APL.L200013 source on the CUBEA13 library tape.
|
|
This should be applied to APL-IMAGE.alg_m after the
|
|
APLPTCH.19710305.alg_m patch above.
|
|
|
|
The 1971-01-11 and 1971-03-05 versions both print two question marks
|
|
("??") at the end of each line of terminal output. These appear to
|
|
represent a carriage-return/line-feed pair appended to the end of
|
|
messages by the program, but translated to question marks by the
|
|
TSSMCP before being sent to the terminal. This behavior appears to
|
|
be something that was missed in the conversion of the APL program
|
|
from the custom data communications handler used by the University
|
|
of Washington at the time to the standard Burroughs TSSMCP. This
|
|
patch removes these extra characters from output messages.
