Is there a free program that codes BASIC (such as QuickBasic). I looked, but I can't find any.

you could look into Rapid-Q- http://www.basicguru.com/rapidq

it is somewhat buggy and it's no longer in development, but it's better than nothing I suppose :P

Thanks... only thing I don't like is that the program window immediately closes when the program ends. Is there a way to fix that?
