Where does $_ come from? Are those keys defined in the hash it references?

    Yes it is!
    $data = ();
   $sql = sprintf $sql_fmt, $account->[$i]{ 'ACCOUNT#' };
   $data = exec_select( $sql );


foreach (@$data) {

      From this snippet and the first one I can understand that data is an array that references hashes. This last snippet shows that data may be defined with the result of the call to exec_select. Still, that shows no guarantee that the hashes in data have the keys $_->{TEST34} and $_->{TEST33}. You may be assuming that they are present, but they are not.

        Yes it could be it, but how could I prevent the warning if they have no value?
