You done that when you have my $thRef = shift #_;
Now to add to the existing array:
$thRef->{'value'} = .....;
When you return from the call and access the data either in the main or
another subroutine the data has been added.
Wags ;)

: You are making a *copy* of the original hash here.
This is the part that puzzles me. I understand *how* it's working but
not why.
What I'd *like* to do is simply declare a local variable to manipulate
the same hash that lives at $thRef (instead of having it populate a copy
of the original hash). Simply to make the syntax within the function a
little clearer. Is this possible? (under -w and use strict?)
