Error description

• An IMS application received the following error while executing
  a BMP writing the output to GSAM TAPE file:
  +DFS1922I GSAM OPEN OF DD VJARIXGS FAILED, REASON CODE=48  BHB1
  IEC205I TAPEDDP,@JARM01B,STEP03,FILESEQ=00001, COMPLETE VOLUME
  LIST,
  DSN=NSDNY0PN.VJDBAIM1.D07086.T192722.PARCHIVE,VOLS=H07700,
  TOTALBLOCKS=6
  A JFCB extension address (JFCBEXAD) could not be accessed
  correctly to find the correct volume when more than 5 volumes
  are specified.  This is because we are running above the line
  (SWA=ABOVE set for JOBCLASS parameters) and the value returned
  in JCFCEXAD field is a token (it representsa SWA virtual
  address) and the token must be converted to a virtual storage
  pointer which points to the actual data area.

  ****************************************************************
  An application failed when an existing GSAM/BSAM data set to be
  opened with DISP=MOD. During open, GSAM/BSAM open/close module
  DFSZD110 got a token of extension volume list when SWA was
  above the line instead of the list's address, therefore the
  application failed.  Furthermore, when the dataset extended to
  the second extension list, the application failed again because
  the module only checked the first extension list.  The
  application failure led to DFS1922I RS=48 which was below label
  VOLERR2 of DFSZD110.

  Modified DFSZD110:  use SWAREG to get the addresses of all the
  extension volume lists.  Loop through all the lists to do the
  comparison which finds the current volser's position in the
  volser lists.  The 31 bit mode is set on before processing the
  extension lists and the 24 bit mode is set back when the process
  is done.
