PM34827: WHEN TRANSFERRING MULTI-BYTE DATA IN FTP, EMBEDDED SINGLE-BYTE DATA IS NOT ALWAYS TRANSLATED USING THE CORRECT SBCS TABLES.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When transferring multi-byte data, FTP uses two sets of
  codepages:  one for the translation of the multi-byte
  characters, and one for the translation of the single-byte
  characters.  However, there are some scenarios, when translating
  from EBCDIC to ASCII, that the EBCDIC newline (hex 15) will be
  stripped from the data instead of being translated using the
  SBCS tables.

  ****************************************************************
  When using DBCS transfer mode, a user is not allowed to specify
  a customized SBCS table using SBDATACONN. This leads to a
  downloaded data set's EBCDIC NL characters not being translated
  to what was specified in the user's SBCS tables.
  FTP should allow DBCS transfer mode to use an SBCS table by
  using SBDATACONN.

Problem conclusion

• FTP has been amended to allow DBCS transfer mode SBDATACONN
  to control the conversion of EBCDIC characters.
