But isn't that just how the world works? As kid I got ERR:MEMORY allot while trying to create games. It was until I started to read a C book which said "We will not use goto in this book. It is a dangerous function that can lead to memory leaks. For example if you jump out of a function, said function will stay in memory because it never finishes." That was the light bulb moment for my TI-Basic problems.
For me the bad part is that the official TI-83 manual has a code example for the GETKEY function that is using GOTO to jump out of a loop.
