PI53281: OPC should not check all subsequent bytes after DEFAULT STOPRBA SEGMENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an SDEP CI has DEFAULT STOPRBA SEGMENT, OPC currently
  checks if all subsequent bytes are zero.  However, OPC should
  perform this check only 1 byte after the DEFAULT STOPRBA
  SEGMENT.
  Also, FPA Analyze currently does not check the byte after the
  dummy segment (if FSOF is zero) and the byte pointed by FSOF
  FSOF (if FSOF is not zero). FPA Analyze should perform this
  check.

  When an SDEP CI has DEFAULT STOPRBA SEGMENT and the FSOF is
  zero, FPO OPC checks if all subsequent bytes are zero.
  However, FPO OPC should perform this check only 1 byte after
  DEFAULT STOPRBA SEGMENT.
  
  FPA Analyze does not check the byte after the dummy segment
  (if FSOF is zero) and the byte pointed by FSOF (if FSOF is not
  zero).
  FPA Analyze should perform this check.
  

Problem conclusion

• FPO OPC and FPA Analyze have been modified to check the free
  spaces of SDEP CIs as follows:
   - If FSOF is zero, then only segment in CI should be a dummy
     segment. The next byte of the end of the dummy segment should
     be zero. It doesn't matter what else is in the CI.
   - If FSOF is not zero, then the byte at FSOF should be zero. It
     doesn't matter what else is in the CI.
   - If SDEP CI is never used, then FSOF is zero and all data
     bytes should be zero.

  The following message is added:
  
  0122: SPACE BYTES NOT ZERO. RBA: xxxxxxxx OFFSET: yyyy - CI
        BYPASSED
  Explanation: The free space in the CI at RBA xxxxxxxx offset at
               yyyy contains a non-zero value.
