  IMS Database Recovery Facility (DRF) provides the following
  support:
  - Allow z/OS to obtain buffers above the 16 MB line at OPEN time
    for non-VSAM data sets with the following DDs that are created
    internally by DRF and OPENed in DRF MAS.
  
   - DFSPRIN@
     Data set for this DD is used when ADD IC is specified and
     High Performance Image Copy is run. This data set is not
     used when RPTTYPE=SAS is specified.
  
   - FABAMS@
   - FABARPR@
   - FABASNA@
   - FRXWT@
     Data sets for these DDs are used when ADD PC is specified and
     Fast Path Basic Tools DEDB Pointer Checker is run. These data
     sets are not used when RPTTYPE=SAS is specified.
  
   - HFPSYSIN
     Data set for this DD is used when ADD IB is specified and the
     Build Index function of FPA is run.
   - HFPPRIN@
   - HFPRPTS@
     Data sets for these DDs are used when ADD IB is specified and
     the Build Index function of FPA is run. These data sets are
     not used when RPTTYPE=SAS is specified.
  
   - IIUIN
     Data set for this DD is used when ADD IB is specified and
     Index Builder is run.
   - IIUPRIN@
   - IIUSNA@
   - IIUSOU@
   - IIUSTA@
     Data sets for these DDs are used when ADD IB is specified and
     Index Builder is run. These data sets are not used when
     RPTTYPE=SAS is specified.
  
   - WRTNSYSN
     Data set for this DD is used when ADD IB is specified and the
     IMS DFSPREC0 utility is run.
   - PRPRIN@
     Data set for this DD is used when ADD IB is specified and the
     IMS DFSPREC0 utility is run. This data set is not used when
     RPTTYPE=SAS is specified.
  
   - PROCCTL
     Data set for this DD is used when ADD PC is specified and
     High Performance Pointer Checker is run.
   - SNAPPI@
   - STATIPR@
   - VALIDPR@
     Data sets for these DDs are used when ADD PC is specified and
     High Performance Pointer Checker is run. These data sets are
     not used when RPTTYPE=SAS is specified.
  
  - Allow z/OS to obtain buffers above the 16 MB line at OPEN time
    for non-VSAM data sets with the following DDs that are created
    internally by DRF and OPENed in DRF SAS.
  
   - FRXWTOIB
     Data set for this DD is used when RPTTYPE=SEP and ADD IB are
     specified and Index Builder, the Build Index function of FPA,
     or the IMS DFSPREC0 utility is run.
  
   - FRXWTORS
     Data set for this DD is used when RPTTYPE=SEP and either ADD
     IC or ADD PC is specified and High Performance Image Copy,
     High Performance Pointer Checker, or Fast Path Basic Tools
     DEDB Pointer Checker is run.
  
  This enhancement enables IMS Database Recovery Facility to
  reduce the occurrences of S878 ABEND in DRF MAS and SAS.
