PK16436: EPI CLIENT GET INCORRECT OUTPUT. SBCS DATA CONVERTED AS DBCS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• EPI client application get gabage output for SBCS data.
  SBCS data converted as DBCS becasue dbcs_screen_map contain
  dbcs_only flag eventhough the fild does not contains DBCS.
  CICS application issues SEND MAP ERASE but CICS does not
  reset dbcs_only flag in dbcs_screen_map.

  ****************************************************************
  A BMS application is run from an EPI client which uses DBCS. A
  BMS map is sent which contains a DBCS field. On the next
  pseudo-conversational leg, a different map is sent with the
  ERASE option. This contains an empty SBCS input field at a
  screen position which is slightly earlier than the DBCS field on
  the previous map. Data is entered into this field by the user.
  When the data is received in CICS, it is converted from ASCII to
  EBCDIC using DBCS conversion instead of SBCS conversion
  resulting in garbage.
  CICS contains a dbcs screen map which tracks the location of
  DBCS fields on the screen for EPI clients. This is used by
  DFHCCNV3 when converting incoming data from an EPI client.
  If a SEND is issued with the ERASE option, this screen map
  should be cleared of all DBCS indicators.
  DFHXTP calls DFHCCNV3 when a SEND is issued but the ERASE
  option is never set. This is because DFHXTP is working with
  the assembler version of the DFHC32 parameter list.
  This is out of step with the PL/X version of the parameter list
  used by DFHCCNV3.
  
  ADDITIONAL KEYWORDS :- C32_ERASE
  

Problem conclusion

• The assembler version of the DFHC32 structure has been updated
  to bring it in step with the PL/X version of the same structure.
