I see. You never know where does the other guy come from. In VB
(yes I am forced to use THAT) the scope is either whole subroutine
or whole file or whole application. Aaaaaggggrrrrrr.

Yes, you can do it that way. What I ended up doing though is start
my scripts&modules with
use strict;
use warnings;
no warnings 'uninitialized';
cause I simply hate that warning. Having to write stuff like:
if (defined $foo and $foo)
Nay thanks.

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
