Re^3: at continue, last

That'll break the program's logic; $loop may only be decremented within the conditional (otherwise, yes, I'd put it outside of it).

I that case, decrement it as the first thing in the conditional, then you're guaranteed it'll happen.

The point is that, as described, there is no reason to employed contorted logic to achieve the described requirement.

Perhaps in an attempt to simplify the original code you've omitted something that makes the contorted logic necessary, but as posted, it simply isn't needed.

I replied to another similar comment elsewhere; `$loop` is used in the conditional, so decrementing it before I use it means I have to increment it every time I use it.	[reply] [d/l]

The point of the posting was to examine different ways of solving the underlying problem, namely ensuring that there's a single path to cleanup code in a conditional, and the obscure means by which it could be achieved. Perhaps that would have been a better introduction.	[reply]

The point of the posting was to examine different ways of solving the underlying problem, Understood. Most times, (though not all), when I find myself coding a tortuous solution, if I can step back from it, or get someone else's eyes upon it, there is a better solution. But almost without exception, if you focus too close on the problematic code out of context, you lose the overview which allows for the clean solution.
