		_________________________________________________________


	I) Description and how to play
	______________________________

		Send snake2.0final.8?g to you TI-83+. In this group are 4 programs : SNAKE, ZSN2, ZSN3 and ZSN4.
	These programs take 477, 183, 354 and 148 bytes (total : 1162) on calc.
		Run ONLY snake.8?p from the prgm menu.
		At the start, you'll see S=?. You have to input the length of your worm (1-99).
		Then move the head with the arrows.
		There's also a kind of teacher key : [Y=]. When you press it (once a game is allowed),
	the game will stop automatically. Then re-run the game, a load-screen will appear. If you haven't
	changed anything in the calc, select [LOAD]. The program will redraw the worm and the
	head will be a "e". Then, push [ENTER] and play ! If you've changed something, 
	select [BACK] and start a new game.

	II) Variables used
