James,
yes it does thanks! Will you be so kind and answer my other question too?
maybe I am not understanding when a multidimensional array would be
useful? when are these references useful?
is there a perldoc I can read as well?

I really doubt you need a multidimensional array here. The first half
of all those lines is the same and since you filtered the output to get
just that, I assume we can throw it away. You just want the codes
after the = sign, right? Let's ask for that:
my @codes = grep s/^barcode=//, `evmvol -w label_state`;
Does that get what you're after?
