Thanks, that's what I thought was happening, but now I have another question.
If I 'use strict' (and who doesn't), I am forced to declare $line before the
foreach loop, except I can't just type 'foreach my($line) (<>)'. I have to type
it on a preceeding line. If this is the case then why does perl localize it
anyway. If i'm declaring it before that loop shouldn't its scope carry through
the loop?
