#  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.
