	Tictactoe
      For the TI-73
       By Skankus
    
I used to think that programming half-way decent games on a calculator was nearly impossible.  But when I finally got this working right, I was pretty impressed.

Installation:
-------------
Simply upload the two lists, POSX and POSY, and the program itself using TI-Graph Link 73. Run the program from the PGRM menu on the calculator.  The lists are needed because I wanted to keep some crap out of the program. It not only minimises the program's size, but it makes it less cluttered.

How to play:
------------

You remember how to play tictactoe, right?  Just three Xs or Os in a row to win. If the board gets filled without anyone winning, it's a draw. The x or o with the black box is your current piece.

Notes:
------

I think the Basic that comes with the '73 really blows. For one thing, there is no way of storing strings (except for lists, but you can only store 6 characters). Also, although there are While loops and the like, there are no Break statements or Continue statements like in C. So I had to do little hacks like using labels at the end of long loops, and using variables to figure out if an IF statement was true (if you try to GOTO out of an if loop, the calculator expects an END, but it can't find it). Like I said, there are several hacks and stuff. It's sometimes better to use nothing but GOTOs.

This game was originally going to have one player mode, but I never got around to it. Also, it is a bit slow when moving pieces, but it's a hell of a lot faster than it was before.

Legal Crap:
-----------

I'm only 15. I could care less what you do with it. If you redistribute this zip file, however, keep the files intact. If you modify it, give me credit (My real name is Evan Flynn). If you like this game, send a dollar to the address below:
