  This apar introduces DRA options for IMS V10. A CCTL will
  specify DRA function level 3 to indicate support of DRA options.
  No new DRA option is being implemented in V10 with this apar,
  only acceptance of the new DRA function level and the DRA
  options fields in the PAPL, and the DFSPRP macro.
  
  ** NOTE **
  CICS TS 4.2 invokes the DRA at function level 3. CICS TS 4.2
  users of IMS V10 will require this apar.
  

Problem conclusion

Temporary fix

Comments

• This change introduces DRA function level 3 which adds support
  for DRA options. No new DRA options are being introduced with
  this apar. Any future DRA enhancements will be introduced via
  DRA options. This should eliminate the need for changes on lower
  level IMS releases to coexist/tolerate enhancements introduced
  in higher releases. This allows CCTLs (ie CICS) to exploit new
  DRA function without needing to first know the version of IMS
  to which it is connecting.
  This can be accomplished in the following manner.
  The CCTL issues a DRA INIT request with function level 3 and
  indicates which functions of the DRA to activate if available
  via the PAPLDROP settings. On return from the INIT call,
  PAPLDLEV will contain feedback on what options have been
  activated.
  Module and macro changes:
  DFSPRRC0 - Modified to accept DRA function level 3 and set
             PAPLDLEV accordingly
  DFSPZP00 - Recompiled to pick up DFSPRP macro changes
  DFSPAC   - Add function level 3 and redefine DRA options field
  DFSPRP   - Reserve and init to 0 potential options fields for
             control block generation.
  DFSPAPL  - Add new field PAPLDROP for DRA options.
             Define additional flag in PAPLDLEV
  DFSAERA0 - Recompiled to pick up DFSPAC macro changes
  DFSAERI0 - Recompiled to pick up DFSPAC macro changes
  DFSPRA10 - Recompiled to pick up DFSPAC macro changes
  DFSPAT20 - Corrected abend0C4 encountered when processing
             an error received during syncpoint.
