segmented string <str> is not started or created

  Explanation:  You issued an END_SEGMENTED_STRING statement using
  a  name  for  which  no  corresponding START_SEGMENTED_STRING or
  CREATE_SEGMENTED_STRING   was   issued,   or   for   which    an
  END_SEGMENTED_STRING has already been entered.

  User    Action:     Issue    a     START_SEGMENTED_STRING     or
  CREATE_SEGMENTED_STRING statement before using
          END_SEGMENTED_STRING, or only  use  END_SEGMENTED_STRING
  once for each START_SEGMENTED_STRING or CREATE_SEGMENTED_STRING.
