If it doesn't matter what key it is then use


If it does matter then just replace scancode with keystate and put the ASCII value of the key you want pressed in the parentheses.

By the way, that source button is evil. It never works. Use the CODE button instead. It'll section your code off like you see above.

The source button does work - you just have to be nice to it!

[Edit]

Actually, I should have mentioned it at the time of posting, but new(ish) members of the forum can't use the Source button method of posting code - it automatically enables itself after a while.

Just use the Code tags in the meantime...

Relativity gives the best solution. Is you use a gosub for a exit of a loop. You gone to stack return adresses. If you do this lot and not using a return statment eventuly your stack will fill up.

For me EXIT is the only way to use. Its a neet option and you don't use resources of any kind.

But DO NOT take it as a final option because TDK is a good programmer and he does know a lot of this. He did make a lot of good tutorials. So if he says it can than it is possible.

Never say a question is stupid. Questions not ask are stupid.

Depending on the type of loop you have, in addition to that posted by Relativity, you can do the following:






The 'exit' command will work on any proper loop (for/next, do/loop, repeat/until, while/endwhile). That excludes loops you make using goto of course.
