We describe a code lengthening technique that uses Unequal Error Protection codes as suffix codes and combine it with iteration of the conventional Construction X. By applying this technique to BCH codes, we obtain 5 new binary codes, 13 new ternary codes and 13 new quaternary codes. An improvement of Construction XX yields 2 new ternary codes.
