Error description

• Abends0c4 DFRNFCD0 INTC 10 when running DFR against 4-GB areas.
  R2 at abend has a large negative number value.  Data at PSW is
  x'1B214420  C59458E0  C8BC07FE'.  DFRNFCD0 was called by
  DFRNFIO0.

  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  The cause of the problem is that DFR compares CI RBA using
  arithmetic instructions in the logic, even if an Area has the
  size beyond 2 GB. If DFR did not get ANENDS0C4 (ie. if RCIBMAP
  DD statement were not specified,) DFR could recover VSAM CIs
  incorrectly for an Area having the size beyond 2 GB, because
  some of the DFR main line modules also use arithmetic
  comparisons for CI RBA. All these comparisons should be changed
  to logical instructions. This problem does not occur for the
  recovery an Area having the size less than or equal to 2 GB.
  

Problem conclusion

• DFR should use logical instructions for the treatment of Area
  CI RBA.
