It was only a couple of years ago since I wrote an assembly language program of my own and got hit by branching-limits on the Z80 processor.

I did exactly the same things that were suggested in this article, either inverted conditionals, or had a thunk - essentially "jmp nextJump", where that jumped to the actual location.

I sometimes spent a few hours shuffling code around to remove the longer jumps and re-order code in groups closer together to save individual bytes.
