in reply to Uninitialized value in string warnings (was: Warnings:)

You could try using diagnostics:-
just add the following to your program 
use diagnostics;

you may need to comment out use strict; and remove the '-w' flag. What diagnostics does is give you a discription of what may be the problem.

In you particular case you are faced with using a possibly undefined variable as you have stated. You could either go ahead with your proposed idea, or "initialise" everything at the start of your code. EG 
$a="";
$b="";
$c="";

Or you could put your potentialy uninitialied variable into a safe state after it is defined and before use eg. 
$b = defined($b)?$b:"";

Hope this helps.

    I'm already using: 

    #!perl.exe -w
use strict;
use diagnostics;

    [download]

    but I don't want to turn off warnings or strict for the whole program to avoid this which I know about and am ready to except.

    See above (or below?) for my reply to the previous poster for why I was trying to avoid the ternary op.

    Thanks.
