PDP-11 Pascal compiler

Archive with the DECUS DEC PDP-11 Pascal compiler, including sources.

This compiler is a descendent of the ZürichPascal compilers.

            DECUS Pascal for PDP-11

	          Version 6.3,  November 1985


This compiler implements the Pascal programming language on PDP-11s
running RSX-11 and on other systems that can run RSX tasks (eg. RSTS,

The main features of this Pascal are:
  - can optionally compile programs to use any arithmetic hardware
  - useful language extensions: default case, loop statement, variable
    length string parameters, substring parameters, structured function
    results, boundless array parameters, and more
  - enhanced I/O facilities for creating and accessing files of
    various types
  - standard file for terminal I/O
  - separate compilation of procedures/functions
  - linkage to external FORTRAN or MACRO routines
  - source "include" facility
  - development aids: statement trace, statement execution profiler,
    conditional compilation
  - high level interactive symbolic debugger and symbolic dump
  - all source and tools provided for maintaining the compiler and
    runtime library (compiler can only be re-compiled on RSX-11).

This release introduces several minor corrections and enhancements.
In particular it now runs on the latest versions of RSTS and RSX.

Several deviations from the ISO/ANSI Pascal Standard.  (Conformance
