Re: Re: opening a file destroys nulling entries in a list?!?!

How come while(<IN>){}, but not for (@x) {}? why is while (<IN>) so special?

I love perl, but this scares the hell out of me.

Nevermend. I think I get it - someone else posted that `while(<>){}` is the same as `while($_=<>){}` - it does an assignment to $_ and that's what does the damage. Somehwere, I think I remember someone (Tom Christiansen, I think) saying to always localize $_ in subroutines. Now I know why. --Bob Niederman, http://bob-n.com	[reply] [d/l] [select]
