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 Algol. The PASCRUN/DISK file
is Algol source that is inserted into the Algol generated from the
Pascal source to provide a run-time system -- actually it is more like a
shim between Pascal and standard Algol 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.
