'    X's and O's by William Yu 1994
'
'  Yes the basic of all basic games, this is an EGA version of
'  the popular X's and O's game (or TAC-TAC-TOE if you prefer).
'
'  WARNING:  Do not adopt this style of programming.
'            I programmed this at school.  It's really messy and
'            again I don't document much of my stuff that is
'            years old, because I don't know what half of it means.
