Kyle, this is a syntactic 'not-nicety' of Perl imho. You need a separate
line like so:
my $key;
This must of course go before the loop, preferably right before it as this
is good style. Hope I don't get flamed to death now. :)
BTW, an alternative that I sometimes use in the case where I need a bunch
of scalars in a sub is to just declare a hash, e.g.
my %vars;
Now I can use $vars{moe}, $vars{curly} etc... to my heart's content with
only the one 'my' variable.
hth,
Marty
