I am very new to TI programming and I am teaching myself how to do it. I have made a simple program which move a 2x2 dot with the arrow keys on the screen. After a min I get the out of Memory error. Is there anyway I can avoid this. Again please be patient and don't post extremely hard to understand answers as I am very new. Here is the code. Also for some reason the store variable button showed up as a U with two dots over it. Please disreguard.
