  ****************************************************************
  PPRC pairs can be established with Incremental ReSynch enabled
  via DSCLI. The PPRC pairs are accepted by GDPS and HyperSwap is
  enabled which may cause issues for subsequent processing.
  
  GDPS would like to be able to obtain the Incremental ReSynch
  status with HyperSwap API function code 16 so that the problem
  can be detected during their monitor processing.
  

Problem conclusion

• HyperSwap API function code 16 is updated to return the
  Incremental ReSynch status byte.
