I'd like to disable the ON key while running a game so the loops cannot be broken...

Is this possible in Basic? If it's something I would have to write in Assembly then has anyone already written such a method?

This cannot be done in pure Basic (at least in a controllable manner). Here's an asm subroutine that does this for you however: linky

Note: Do NOT use this unless you are sure your program is completely bug free.

Great program, just make sure you have an exit :P...

yea true i remember trying a program jbirk on uti made like this back in 2003 and forgot to add an exit in rl3 XD
