Readme-Shade This program simply shades your TI-83 screen and repeats it over and over. If you just want it to shade your screen once, then go to the end of the program and delete the pharse telling the program to repeat (prgmSHADE). It can be used as a screensaver when you make it repeat over and over again. This program is not protected so edit it to your perfection. It is pretty hard to describe so put it on your calculator to see exactly what it does! By Tony Lu
