I'm very well aware I've broken a number of programming conventions, and this may be a pain to read.
Anyway, I'm getting the following error: bios:338:[string:"startup"]:66: 'end' expected (to close if on line 64)

Any help?

You added an until line between an if and its end. You can't do that. And I don't know how you would fix it, but given you've written this, I'm betting you can figure it out.


EDIT: Actually, I did figure it out. Use while instead of until. Or a for loop.
