Hello toolic,

The only thing you do with the variable is pass it as an input to your countThem sub.

Yes, but the variable $tmpfilecount is a package global (no my in sight, as you note), and within sub countThem the variable $_[0] is an alias to the variable passed as the first argument. Therefore the line:

$_[0]=$filecount;

[download]

within the sub actually should change $tmpfilecount to the value of $filecount. Proof of concept:

 0:42 >perl -wE "sub f { ++$_[0] } $x = 42; f($x); say $x;"
43

 0:43 >

[download]

So the problem is that $filecount is never incremented.
