  In base V14, 64 bit high speed utilties were not supported by 64
  bit buffers during /ERE.  31 bit buffers were used.  This line
  itemm adds support for 64 bit buffers during /ERE for 64 bit hig
  speed utilities
  

Problem conclusion

• This APAR will use 64 bit buffers during /ERE if the log records
  being processeed were for a HSSP or HSRE utility utilizing 64
  bit buffers.  The 5950 has a new flag, which tells /ERE that
  this was logged by a 64 bit High Speed utility, to the 64 bit
  utility buffer manager will be called to allocate the buffers in
  64 bit storage.
  
  DBFDMAC
   - added trace entries for the DMAC byte trace
   - added DMACFH64R so we know we obtained 64 bit pvt pool
  
  DBFDMHR
   - added DMHRHF_64B so we know DBFPAPB1 allocated
  
  DBFESCD
   - ESCD_FPTK_F4_REDO added for FP toolkit
   - ESCD_64_F3_6HOFF added to disable 64b for /ERE
  
  DBFLSRT
   - DLOGF26U (EPS2F26U) so we know this 5950 is for 64b
     pvt utiltiy buffers
  
  DBFPGAB0
   - Updated code to NOT clear DMHRHF_64B when DMHRHFLG cleared
  
  DBFERDB0
   - Added DBFUHSW
   - If 5950 for 64 bit pvt HSxx buffers and DMACFH64R=0, we call
     ALOC64S -> DBFCST00 -> DBFCST10 to allocate a 64 bit memory
     object.  We then set DMACFH64R.  Once allocated, we call
     DBFPAPB1 to obtain the pvt buffer pool, then turn on
     the 64 bit DMAC flags (DMACFH64 and DMACFH_REDO6)
   - When extending pvt pool we call DBFPAPB1 (instead of
  DBFPAPB0)
     if DMACFH64 is set on
   - If we clean up, we call DBFPFPB1 then RELUHSW if DMACFH64 is
  set,
     and then reset the 64 bit flags
   - ALOC64S added to obtain the UHSW and allocate the 64 bit
  memory
     object by calling DBFCST00 -> DBFCST10
   - RELUHSW added to release the UHSW.
  
  DBFEROC0
   - If DMACFH64 is set, we call DBFPFPB1 to release the UHSW, and
     then DBFCST10 to release the 64 bit memory object
   - Added RELUHSW to release the UHSW
  
  DBFERS20, DBFMUTR0
   - converted ERS2DMHR into a subroutine
   - converted ERS2DFCI into a subroutine
   - converted ERS2ABND into a subroutine
   - Added check for DMHR_64_F2_64BIT and if on issue 64bit DFSIOT
  call
   - turned on DMAHCFE_REDO if redo called
   - add code, if FPTK on for REDO, and REDO performed call
  FPTKWTO to
     issue a WTO with the AREA name
   - Added code to also check for DMHR_64_F2_64BIT to know we need
  to
     load the 64 bit pointer.  Restructured the IF/ELSE for 64 bit
  vs
     31 bit.
   - Added FPTKWTO to echo a DBF0000I test message with the area
  name
     for tester use
  
  DBFCST10
   - Cleaned up register usage to make consistant with callers
  
  DBFFATC1
   - Added support for FPBP64HOFF keyword.  The only option is
  'Y'.
     This will disable the 64 bit /ERE code.
  
  DBFSLGE0
   - Added check, if DMHRFH_64B set, we turn on EPS2F26U in the
  5950
     (DLOGF26U) for /ERE to use
  
  DBFTOOL2
   - Added support to enable the REDO toolkit
  
  DBFPAPB1
   - Added code to turn on DMHRHF_64B, so we know this is a 64 bit
  HSXX
     pvt buffer, and not another pvt or 64 bit buffer.
  
  DBFPHST0
   - Changed PST on call to DBFCST10 from R7 to R9 to be comptable
  with
     other callers of DBFCST10
  
  DBFUHRE0
   - changed DFSDUMP call to use ABU1028 rather than literal
   - removed unneeded comment
  
  DBFUMRT0
   - removed unneeded comment
  ----------------------------------------------------------------
  ---
  Doc change
  Added new FPBP64 parameter
  FPBP6HOFF = Y
    When specified, this option disables the 64 bit /ERE code for
  the
    64 bit HSSP and HSRE utilities.  When HSSP or HSRE used 64 bit
  pvt
    buffers, and IMS is /ERE'd, emergency restart will use the
    (pre-existing) 31-bit pvt utility buffers for redo processing.
  
  DFS1919I message
    FPBP6HOFF has been added to 'aa' in the message explanation
  
    for /ERE processing
