Good Monks. I have the following bit of code:

while (my @row = $sth_C->fetchrow_array) {

      print OUTPUT_FILE join("\t", @row);
      print OUTPUT_FILE "\n";
      
      undef @row;
}

Which I would like modified to check to see whether the array @row is within an array of arrays called @collection_of_rows. If it is I want it to exit the loop and if it isn't I want it to continue as before and add @row to the array of arrays.
