Extending COBOL with Scheme and Brainfuck (opencobol.org)

APL extensions for OpenCOBOL sounds like a grand idea.

Just built the newly GPL'ed version of JSoftware's J announced by Eric Iverson. I'll give it a try.

Ok, first cut. Don't know enough APL (J) yet to get output to prove it's working, but it inits and evaluates 1 + 1 without any error codes.

Life can be a lot of fun.


Extending COBOL with Brainfuck is wonderfully twisted, but you know what I want? A Brainfuck-to-COBOL interpreter implemented as a Turing Machine. Now, there's a nice weekend project for somebody....


No APL? Now that would be an awkward marriageā€¦
