  ****************************************************************
  HP Image Copy terminates with ABEND S0C4 ( ABEND0C4 ) in
  FABJMAIN at offset X'16F0'.
  
  The cause of the problem is as follows:
  - HP Image Copy calls DFSRRC00 from FABJMAIN in AMODE
    (addressing mode) 31.
  - DFSRRC00 changes the AMODE from 31 to 24, and the control is
    returned to FABJMAIN in AMODE 24.
  - FABJMAIN causes the ABEND S0C4 ( ABEND0C4 ) when referring the
    storage area above 16 megabytes.
  

Problem conclusion

• FABJMAIN has been modified to switch the addressing mode from 31
  to 24 before calling DFSRRC00, and switch it back from 24 to 31
  after the control is returned from DFSRRC00 to FABJMAIN.
