  ****************************************************************
  After getting a message from a queue, a channel attempts to
  convert its headers in to the coded character set id (CCSID) of
  the remote end of the channel.
  In the failing case the message had been put by an application
  with @ in the jobname (x'7C') and was being got by a svrconn
  channel running in CCSID 1208.
  Conversion of the PutApplName failed, because the queue manager
  was running in an EBCDIC code page (in this case 1141) where the
  @ symbol is at a different code point, because the character at
  x'7C' (for 1141, the section symbol) required 2 bytes when
  converted to 1208.
  This caused the conversion to fail because the converted
  PutAppName field required 9 bytes, but the field was only 8
  bytes long.
  

Problem conclusion

• CMQXRMCV is changed to correctly handle messages put by a batch
  job with jobnames containing characters that are variant in
  EBCDIC codepages (@ $ and #).
