Tic Tac Toe Version 3.0
Readme
By Lucas Yerpe

This is a user-friendly, one-calc, two player tic tac toe program.
Here's how to play:
 -Select "new game".
 -Press '+' to enter new player names. (Later, press '-' to keep the
  current players.)
 -Type the player names.
 -Use the number pad to place shapes in the squares. For instance:
  1 is the bottom-left square, and 5 is the center square.
 -When the game is done, you can either look at the scores for the
  session or just start a new game.
 -If just one player wants to be replaced, put in the same name for
  the same shape, and that player's record will be kept. The new player
  will start with no wins.
 -If the calculator breaks the program with an ERR:MEMORY message, just
  start the program again. The records will be erased. The more RAM you
  have free, the longer you will be able to play without interruption.
Enjoy!
