in thread A Warning Issue!

At the risk of adding more bulk to your code, try this check first, as well as one for $_-> { TEST34) }.

if ($_->{ TEST33 } ) { <your previous code here ...> }

Your wish is my commandline.

    I could use something like that for all that apply as well, right?

    if(defined $_->{ TEST33 } && $_->{ TEST34 } && $_->{ TESTX33 }) { <Previous code here ...> }

    Just don't forget the implicit assumption here that $_->{TEST33} will never be zero. If zero is a valid (or even possible) value, you probably want to test if (defined $_->{TEST33}) instead.
