Got it compiled with gpc (GNU pascal compiler) and it "runs", but the move
syntax is some kind of screwed up descriptive notation.  It could be the OCR
process made some workable typos or some of the program is missing.  You can't
actually enter a valid move, so it makes a move for you.  It moves instantly and
you can't tell if it is doing any kind of meaningful search.  There is no
obvious command table.

I can't make heads or tails of it.  One would need to study it a little to fix
it up.
