  ****************************************************************
  When message properties or selection strings are converted from
  a String to other data types e.g. Boolean, Float, the qmgr ccsid
  is used. In some CCSIDs, such as 5026, the lower case characters
  are found at a different codepoint to most other EBCDIC CCSIDs.
  The conversion process does not account for this, leading to
  errors if the value being converted involves lowercase
  characters.
  

Problem conclusion

• CMQXCNVA is changed to detect when converting to/from a CCSID
  where the lowercase characters are in a different codepoint to
  the compiler's CCSID and correctly handle it.
