ITERATE requires label "<str>" to be on a looping statement

  Explanation:  ITERATE must reference the label of a looping
  statement such as a WHILE, LOOP, REPEAT, or FOR loop.  The label
  used, or defaulted, is the label of some other statement.

  User Action:  Correct the label referenced so that it is that of
  a looping statement or use an explicit label from a looping
  statement.
