here is the sample output.

maybe I am not understanding when a multidimensional array would be useful? when are these references useful?
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?
