Yeah, that's right. I'm back, and I have something to say. This is really a reply to people who've given code examples in this thread.
I don't understand the last line of:
And I don't understand the point of:
I've had numerous problems trying to determine where a global was changed, and I have a feeling there's a good anti-global argument around here somewhere, but I can't find it. When a script is doing alot of calculating and outputting just the end result, I don't think it matters how localized things are. You still won't know what affected the output.
Another, barely related thing--I'm just about done with a GNU tar GUI for Windows, and I'm finding good uses for goto all over the place.
Anyway, please make your code examples as simple as possible and explain them properly.
