Hero Zzyzzx said: You could declare the variables as globals...but this is bad programming practice generally, as I understand it. (why is this? Is it due strictly to memory usage?)
You answered your own question as to why globals are bad, when you said You can reuse the [code] elsewhere, 'cuz you know exactly what goes in and what comes out.
