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?

James
