  CSQAVICD or CSQAVD64 returns a DataLength value set to the
  length of the converted message that could be stored in the
  buffer rather than the length of the unconverted message.
  

Problem conclusion

• CSQAVICD or CSQAVD64 returns the length of the unconverted
  message when the converted message is truncated.
  
  This fix is applicable to Batch, IMS and CICS applications.
