Has anybody written a tic-tac-toe program?

        I also have written a tic tac toe program.  It was my first
attempt at writing a game in pascal.  I was able to write a two player
mode quite successfully, but the person vs. computer mode was less than
adequate.  I to am a 17 year old programmer.  By the way, this is my
Mom's login, I use it for higher security levels.  Write me back if you
want more info.
