If there's no digit in $_, then $1 will be undef (or worse; see
below). I think that's probably your bug: Some filename isn't like the
others. Instead of this:

You are using the results of a regular expression match without verifying that
the regular expression matched s

That's not an error, but a warning. You will find that execution goes
after this.

How do I avoid this error?
a) Initialize it :)
my $num = 0;
b) don't use warnings - but don't do that
c) turn off uninitialized wanring

using -w or
use warnings; in your script that is causing the warning.

Hi Nikola/Jason
Thanks for the help.
The variable $result_value1 is declared within the subroutine and is never
used outside the subroutine.
