Use of uninitialized value in concatenation (.) or string at JFS_version_parser.pl line 20, <JFS> line 952 (#1)
This message happens because some value was undef instead of a string.
From the message, it seems likely that it's a variable being
interpolated into a string. Once you find out which variable, and why it's undef, and that it doesn't matter whether it's undef or an empty string, you could fix it something like this: # avoid messages about uninitialized $whatever $whatever = "" unless defined $whatever;
use strict; use warnings; use diagnostics;
The first two are great. The third one is not intended for production code; you should 'use diagnostics' only when you're developing code and expecting error messages. I say this in part because 'diagnostics' has a significant overhead of both time and memory. Be sure to disable it when your code goes into production.
You have mail.
