XPL compiler ported to Intel (on FreeBSD)

Hi,


I've dug out a rather old compiler/compiler generator called XPL, and
ported it to the Intel 486. It's documented in the book "A Compiler
Generator" by McKeeman, Horning and Wortman, published by Prentice-Hall,
1970, ISBN 13-155077-2. The original compiler was designed for the IBM
S/360. The language is XPL, a dialect of PL/I. The compiler is written
in XPL. The package constain the compiler, bnf grammar, grammar analyzer,
skeleton compiler, S/360 emulator to bootstrap the build, and all source.


It was ported on a FreeBSD Unix system, so I suspect that other BSD
variants will require a few changes, and Linux a few more.


It's available from:

Thanks,

predecessor of C not particularly for its design but for what people used it
for. -John]
