pop ebxI'm pretty confident that the use of "goto" in assembler is de rigueur. :)

goto[^] I've only used goto once before as a professional and ended up removing it a few minutes later when I figured out a different way. Sometimes though for simplicity it just makes sense. I think I'll leave it! Anyone who thinks this code should not be checked in, speak now or forever hold your concurrency locks.

In any decision where I have two blocks of code that are functionally equivalent but one is more nested than the other, I will pick the less nested version. Fewer braces overall in the code.

1991 was the last time I used GOTO, and I was not a professional then X|

I have, but in scripts (e.g. DCL and BAT files), not in proper programming languages. Except for VAX BASIC, but maybe that stretches the definition of "proper programming language". :~

Protip; bugs should be reported[^] bug forum instead of on the lounge.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies. -- Sarah Hoyt
