PK51354: ABEND S0C4 IN MODULE=FRXRLRA0 OFFSET X'1624'

APAR status

• Closed as program error.

Error description

• The abend occurs on the CLC instruction at offset +x'1624' of
  module FRXRLRA0 which is at PK45811 level.
  
  This is the instruction "CLC  LCL_DBD(8),RWCR_DBD_NAME(@07)"
  and we are trying to compare the DBD name PLA2P0HT pointed by
  R13 with the one in the RWCR pointed by R7. Our R7 at time of
  abend contains x'780' which is the result of a previous sum with
  R3 being x'780' and a zeroed R4.

  A prior sort had failed with returncode=18 (RC=18) as reported
  by message
  
  FRD0001I FRXI0003 FRD3001I UNEXPECTED RETURN CODE FROM
  SORT, RC=18
  
  in the job sysout. DRF overwrote the bad sort return code 18
  with a return code 0 from a diagnostic call, so continued
  processing until an unpredictable result occurred, in this case
  an ABENDS0C4.
  

Problem conclusion

• DRF logic was changed to restore sort return codes to their
  correct value, so the correct error processing path could be
  taken.
  

Temporary fix
