Kevtiva Instant Chat  v2.1
(C) 1999 Kevtiva Interactive.
TI-83 Basic

Features:

	-Fast 2 player chat room
	-All TI-83 Basic characters available
	-Get new messages every time you send a message
	-360 bytes (CHAT.83p) 39 bytes (ZALPHA.83p) (Total: 399 bytes)
	-Deletes all the variables it uses
	-Automatically presses 2nd + ALPHA, so you don't have to
	-Messages are saved, until the other person reads them
	-Multiple messages are separated by dots
	-Type exit to quit and delete all the variables
	-You don't have to talk out loud at all

Instructions:

Send CHAT.83p and ZALPHA.83p to 2 calculators.  Keep the calculators linked, 
and then run Chat. Type anything, and press enter to send the message, and
receive any new messages. If the program doesn't work, be sure the link cable
is firmly attached to both calculators, and then restart Chat on one of the
calculators.

To recieve a message without sending a new message, just type a space, and
press enter.  If the link cable comes out while you are chatting, just plug 
it back in and the program will still work.  If you stop receiving messages, 
be sure the link cable is in all the way.  If you accidently stop Chat 
on one calculator, simply restart it, and it will work fine. To quit Kevtiva
Chat, type EXIT.

If you get an err:syntax message, select quit, and the program will say that
ZALPHA is missing.  Simply send it to your calculator.  If you don't want
ZALPHA, edit chat in Winlink 83 and delete this line--it appears twice
in the program:

Send(9prgmZALPHA

This program uses A and Str0-Str3.

>>>Warning!  If you run Chat from SOS, only quit chat by typing EXIT or
pressing on. If you Press 2nd + quit, or let the calc turn off while running
Chat from SOS, you risk losing 678 bytes of memory! :-(

>>>Reset your TI-83's memory to 'reclaim' it, if necessary.

Known Bugs:

	-Twice when I was chatting, I got an error message, and I discovered
	that Str2 deleted itself.  I don't know how it happened, because 
	Str2 is only deleted at the end of the program.  If anyone finds out
	why this happens, please let me know.

	-While chatting using this program, it is possible to deliberately
	mess up the program. This bug won't occur during normal chatting, but
	if 2 people repeatedly send the exact same message to each other, the
	program might not work.
