I've just run onto (with the aid of a friend) some FOCAL code, if anybody would
like to look at it. I'm working on getting that FOCAL interpreter for the 6502,
specifically the APPLE][ running APEX, in machine readable form, but ran into
these bits of FOCAL source code for FOCAL-65, which was patterned after DEC
FOCAL.
Email me and I'll send you the ZIP file containing them.
