I've slightly modified the code you posted for the array, and it's working pretty well. Here's what I've done...

print "\nEnter a brief description:  ";
  my $desc = join('', <STDIN>);
  my $pg_array = join ('', map {split ' '} $desc);
  
  $pg_array =~ s/, $//;
  $pg_array = "{$pg_array}";
  
  print "$pg_array\n\n";
  
  $sth = $dbh->prepare("
    INSERT INTO $tbl_name (product_id, model_number, description)
    VALUES (?, ?, ?)
  ");
  
  $sth->execute($prod_id, $mod_num, $pg_array);
  $sth->finish();

I really cannot afford seperate columns, as the description will contain more than just CPU and MHZ. My plan is to use only ONE table for CPU, RAM, HD, Monitor, case, NIC, MB, and videocard.

Thanks.
