Can someone explain exactly how these work? Can u just put gosub everytime you want that code to run? and RETURN to resume?

Use GOSUB to go somewhere. Then use RETURN to go after the GOSUB command.

Ok, well thats what I thought, then how do stack overflows occur? swear I had it set up right but still got one.

I am not sure. That problem only occured to me a few times.

ok, well thanks for answer anyway! :)
