I know that if you want to search a hash for a key you can use:

 exists($barcode_hash{$barcode_pair_35})

However, my hash has become more complicated:

 $barcode_hash{$prim_pair_number} = [ $fowprim, $revprim, $bc_pair, $bc_pair_num ];

How would I search through this hash to find a particular

$bc_pair

?

My hash looks like this: 

$VAR1 = {
          '1' => [
                   'AGCTCGTTGTTCGATCCA',
                   'GAGAGATAGATGATAGTG',
                   'TTTT_CCCC',
                   0
                 ],
          '2' => [
                   'AGCTCGTTGTTCGATCCA',
                   'GAGAGATAGATGATAGTG',
                   'TTTT_AAAA',
                   0
                 ]

The thing I am looking for

$barcode_pair_35

is this TTTT_CCCC.

Also, when I find it, I would like to increment

 $bc_pair_num++
