This hacked version will run under UNIX, and under DOS as well.  It
should run out of the box on DOS as long as you stay in the current
directory.  See the README file.

This is a test version!!  In accordance with the author's wishes,
I'd like to make it clear that I've altered all the screen I/O
routines, and have removed characters peculiar to VT terminals.
I've tried to keep intact the author's indentation and brace style.
Changes, where present, have been indicated by my initials.  The
IPL-style header was added by me.
