Re: Getting (famous) error during running perl script

[derby]

You concating an uninitialized variable on line 56 ... that's pretty plain. :-)

Maybe an example would help:

#!/usr/bin/env perl

use strict;
use warnings;

my $foo = "foo";
my $bar;  # $bar is uninitialized -- it has no value.

my $foobar = $foo . $bar;

This could be harmless or devastating ... it really depends on what your code is doing and wether or not you expect/need the variable to have a value or not.
