Hi, I'll go by Ti- GBR
I've used the site to learn basic to I'll say a little less than average proficiency
You can call a program that you're running from within itsself by calling the program from the homescreen, then using 2nd enter in the program editor It creates an endless loop, although It may create a mem leak
//Prgm Q editor
Prgm Q //(2nd Entry)
Also, I was wondering, Is there any way to do asm on a Ti 83 ( not +)?
