N2 - It is shown that world-sheets violate the Peccie-Quinn symmetries associated with some of the axions that arise in superstring compactification. In the case of unbroken low-energy supersymmetry, the Peccie-Quinn violating operators that arise are D terms of dimension six. One remaining axion is unaffected.
