I'm trying to declare a zero size hash so a sub function can populate it and
be see by all other sub's.
my %loginHash();
But the use strict doesn't like it. All examples of making a hash
structure is hard coded in the program or is made reading from a file. When
I try to run the script all I
Just write it like:
my %loginHash = ();
This should work.

update your address book and distribution lists
accordingly. Thank you.

I think you need to do:

my %h = 1;
my %h = abacate;
you end with a hash
