Anyone have a good link routine for the TI-83 and TI-83plus (one that error checks for a good connection)? I will give full credit to anyone who can give me a good routine that I can use in my games. Please provide some good documentation (preconditions, postconditions, etc.). Thanks. Hamster1000 theglobe.com Your friendly full-service integrated online community. http://www.theglobe.com
