PK28436: EXEC CICS WEB CONVERSE RETURNS INCOMPLETE, SHORTER, DATA LENGTH

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer uses LOCALCCSID of 937. Application issued WEB CONVERSE
  but received shorter length of data.
  .
  The problem appears to be in DFHWBCL.
  After converting the data, wbo_set_buffer2.n is set to
  ccnv_source_buffer_n instead of ccnv_target_buffer_n.
  .
  Usually these are the same but with DBCS conversions the target
  can be larger than the source data due to the insertion of SO/SI
  sequences.

  ****************************************************************
  An EXEC CICS WEB CONVERSE or RECEIVE has been issued using the
  SET option. The codepage being used is a DBCS codepage and there
  are DBCS characters in the returned data. When the data is
  converted from ASCII into EBCDIC, SO/SI characters are inserted
  into the data but the length returned does not include the SO/SI
  characters. When the application accesses the data using this
  length, it does not receive all of the data.
  Additional Keywords: SOSI SO SI
  

Problem conclusion

• DFHWBCL has been changed in translate_mbcs_block so that the
  correct length is returned to the caller.
