Error description

• While performing TVS processing, it is possible to receive an
  ABEND0F4 in IDAVRR10 when using an RPL for multiple requests.
  If the user's RPL comes in still pointing to a dataspace RPL,
  IDAVRR10 will check if the RPLX_ACTV flag is on, before checking
  if the dataspace RPL is valid.
    Since the comparison wasn't made a request can come in
  pointing to a free'd up RPL or random storage that IDAVRR10 will
  try to use as the dataspace RPL.  Further down in the code
  IDAVRR10 will detect an invalid dataspace RPL and assign a new
  one to the user's request.

Local fix

• To work around this problem ensure an ENDREQ is issued at the
  end of a series of requests.  For example, ensure the ENDREQ is
  issued on all active RPLs before the dataset is closed.  Upon
  closure SMSVSAM will free up any dataspace RPLs still associated
  with the dataset, so if any user RPLs haven't issued ENDREQs
  they will point to storage no longer belonging to that request.
  
  This fix has been incorporated into the base code of z/OS 1.13
  and above.

  WHEN A TVS RPL IS USED FOR MULTIPLE REQUESTS, THE RPL MAY BE
  PASSED TO MODULE IDAVRR10 WITH A RESIDUAL DATASPACE RPL POINTER.
  MODULE IDAVRR10 ISSUES ABEND0F4 PRIOR TO DETERMINING THAT THE
  DATASPACE RPL ADDRESS IS INVALID.
