here is the sample output.
barcode=E01124
barcode=E01178
barcode=E01195
barcode=E01225
barcode=E01232
maybe I am not understanding when a multidimensional array would be
useful? when are these references useful?

Perl arrays are not multidimensional. Using references though, we can
get there.
Backticks return LINES, not fields. If we want to break them down,
we'll need to do that.
Can you show a sample output of `evmvol -w label_state`?
