  ****************************************************************
  As part of DLUR/DLUS pipe deactivation any queued work elements
  (RUPEs) associated with the DLUR are freed.  Each time a RUPE is
  freed, a VIT record (RDSC) is cut to give the address of the
  work element and a reason why it is being freed.  In this case,
  the subroutine was called to free a RUPE, but no RUPE pointer
  was passed in.  An ABEND occurred in the module which attempted
  to write the VIT record because the RUPE address was 0.
  

Problem conclusion

• ISTDLCSA has been modified to make sure a RUPE address is
  present before trying to write the VIT RDSC record and free the
  RUPE.
