in reply to Using open in for loop

That is not perl code. It won't even compile.

I assume you mean something more like this:

use strict; use warnings; my @array = qw/ foo bar baz blah /; for(my $i = 0; $i < @array; $i++) { print "$i $array[$i]\n"; }
Which is fine but this is better:
use strict; use warnings; my @array = qw/ foo bar baz blah /; foreach my $filename (@array) { print "$filename\n"; }

Please notice I added use strict; and use warnings these are a MUST when you are learning perl.

Also notice I did not use the actual open - I simplified to find the real root of the problem
