8-bit acorn software: other • Re: How to detect that I am using the second processor?

Also, just as an aside, if my program fails for reasons A, B or C, I should be free to choose my own error numbers, not try to shoehorn them into some arbitrary numbering scheme devised by Acorn. So you're running MY program and it fails for reason A and I throw a BRK at you with an error number N. MY documentation will tell you what that means. Nothing to do with the Acorn OS. NO NO NO NO NO NO…
