Since SNOBOL came up in two threads in one week;


I've done a free port of the "Macro Implementation of SNOBOL4" that
makes full SNOBOL4 (with many SPITBOL extensions) available on just
about anything that has a C compiler. Not to put down Catspaw
SPITBOL, a professional quality tool (which beats my SNOBOL by a
factor of between 6 and 30 depending on the program), which I used to
bootstrap my system. See my page at


http://people.ne.mediaone.net/philbudne/snobol.html


However as much I like using SNOBOL for one-off text processing jobs,
I'd be remiss to not to point out the implementation of a PDP-1
assembler with a macro processor (written to assemble "spacewar" for a
Java PDP-1 simulator) in Perl;
