in reply to Getting (famous) error during running perl script

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.
