Re: Re: Re: Can this If/Else be condensed into a 1 liner with a trailing If?

Well spotted, and quite correct. When dealing with numbers I tend to step to a higher level of paranoia, simply because zero is a number, but it's not true. This paranoia occasionally wears off onto the code around it. ;)

Cheers,

Actually, whithin a `while (<STDIN>) {...}`, the `$_` contains the trailing `\n`. So even though a line might contain a lone zero, it will indeed be `"0\n"`, which is definitely true. --bwana147	[reply] [d/l] [select]

But a textfile could be malformed and missing the \n at the end of the last line (most Windows text editors forget to put a \n at the end of the last line) thus $_ could contain "0"	[reply]

The question wasn't "can <STDIN> return FALSE" but rather "isn't there some magic built into `while(<STDIN>)` that makes it test for definedness instead of truthfullness?" -Blake	[reply] [d/l]
