CHESS for the TI-83 Plus

     This is a CHESS program for the Ti-83 Plus (as if the name didn't give it away). It has a number of unique and useful features not available in other CHESS programs. Here is a list of it's features:

• The program keeps track of what pieces have been taken. The pictures of the taken pieces are shown in the upper right hand of the screen, in the order that they were captured.
• You can castle. (see instructions below)
• You can take back turns. The number of turns that can be taken back can be changed, depending on your memory requirements. By default, up to 100 turns can be taken back.
• The program only uses 2 programs and 1 picture on a permanent basis, so you don't have 10 programs cluttering up your calculator.
• You can save games

     Here are some facts about the program itself:

• It uses [A] and [B], along with some lists, but they are temporary and are deleted if you exit the game through the menu.
• You can set how many turns can be saved for redo. Each turn takes up about 10 RAM. By default, 100 turns are saved.
• You can save and load games. There is one saved slot, which is stored in list CHESS and Pic 7. in total it takes up about 2000 memory.
• The game doesn't look to see if a king is in check or checkmate, so, in order to win, you have to actually take the opposing king (sorry, but that slows down the game a lot).
• The game takes up a total of 8918 bytes of RAM. When you play, an additional 3024 bytes of memory are used, for a total of 11942. If you need space, you can decrease the amount of turns stored for redo. Each turn takes up an average of 10 bytes. There is a minimum of 1 turn to be stored.
