There's nothing obfuscated there. Perhaps the 1 in void context is confusing you? It can be avoided as follows:

while (-1 != wait) {}

Maybe it's just me, but I find `while (wait != -1) {}` more natural than `while (-1 != wait) {}` since 'wait' is what I want to check :o) -- Time flies when you don't know what you're doing	[reply] [d/l] [select]

It helps to debug typo mistakes (language independent). If you was doing a regular compare '==' but used '=' instead, then 'wait = -1' will assign -1 to wait which could cause run time problems later on. However, if you do '-1 = wait' the compiler will throw a syntax error because you are trying change a constant.	[reply]

Good point, except you "can't modify wait in scalar assignment" either, or atleast that's what perl says when I try. For variables though, I see what you mean. -- Time flies when you don't know what you're doing	[reply]
