a) Initialize it :)
my $num = 0;
b) don't use warnings - but don't do that
c) turn off uninitialized

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

@files probably contain

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

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:
my @files =*;
Consider something like this:

Hi Nikola/Jason
Thanks for the help.
The variable $result_value1 is declared within the subroutine and is never
used outside the subroutine.
I originally had
changed the above code to the following and it worked (Use of
uninitialized value error message did not appear):
$result_value1 = $database1{$input_key1} || ;
if ($result_value1 ne ) {
$a= substr($result_value1, 0, 8);
$b= substr($result_value1, 8, 2);
$c= substr

I think a better way to accomplish what you're trying to do is simply:
my $result_value1;
if ($result_value) {
12 matches
