You can protect individual programs (not whole groups--groups have to be
broken into the individual programs) by opening them in Graph Link, then
checking the "protect" box in the window for the program. Then, when you
download the program to the calculator, GOTO is disabled, and you cannot edit
the program. It can only be run.

This can be done for the 82, 83, 86, 89, 92, 92+. Not easily for the 85.
