# Algol 60 Compiler
## PAL Abstract
850816 9-SERIES 910/925 ALGOL 60 BASIC 4K SYSTEM
AUTHOR: XEROX
ABSTRACT:
@@ -6,24 +8,37 @@ COMMENTS:
SOURCE LANGUAGE: META-SYMBOL. CONFIGURATION: 910/925 COMPUTER WITH AT LEAST 4K MEMORY,
TYPEWRITER AND PAPER TAPE I/0. SEE MANUAL NO. 900699.
## Introduction
This is a compressed source deck for the compiler. It seems to be missing the
interpreter and run time and the Algol Operations Manual. The compiler will produce a
program listing and a card punch file. The PAL manual abstract for cover number includes
numbers for other parts but these are not found on the M300-1982128 tape
850816-44 is compressed source code and has 4 ^ type control cards preceeding the encoded deck.
The algol.si, .bo and .lo files were obtained by uncompressing and assembling this -44 file.
## Reference
http://www.bitsavers.org/pdf/sds/9xx/lang/900699C_Algol60_Ref_Nov66.pdf
## Problems
The original source code has TOPW 1 which caused an assmembly error. It was changed to TOPW.
There is no transfer address on the END card so the loader will halt after loading.
The algol.ini configuration file allows one to do a compile and produce a listing on TTO and an
object deck on CP. Refer to this for Breakpoint settings and the compile procedure.
## Usage
# dep bpt1 1 down, use card reader
# dep bpt2 1 down, use card punch
# dep bpt3 1 down, type source
# dep bpt4 0 down, call objty before codout? Don't set this
Regardless of what the PAL Manual says, 850816-44 is only the Algol Compiler.
I can't find any product to load or execute the object program.
The algol.ini configuration file allows one to do a compile and produce a listing on TTO and an
object deck on CP.
The prime.si file is copied from the example in the Algol Reference Manual. The prime file is
a Hollerith card deck that can be attached to the CR device as compiler input.
The PAL manual describes 850690 as an ALGOL line printer library routine. Both the -24 (binary)
and -34 (source) files are included here. This seems to be a part of the Runtime Library and there
is not comments in the code mentioning Algol.
