  ****************************************************************
  RECOVER utility found a SYSCOPY record with ICTYPE=M STYPE=R
  with a START LRSN that is newer than the time of recovery.
  This ICTYPE=M STYPE=R TTYPE=N record was inserted for a MODIFY
  RECOVERY DSNUM x DELETE DATE(yyyymmdd), but the START LRSN is
  much newer than the DATE passed to MODIFY RECOVERY causing
  RECOVER to fail issuing DSNU556I and ending with RC8.
  
  A SYSCOPY record with ICTYPE=M STYPE=R TTYPE=N is inserted when
  MODIFY RECOVERY did not delete any record from SYSLGRNX. But,
  MODIFY RECOVERY incorrectly picked up a STOP LRSN value from a
  SYSLGRNX record and saved it as the START LRSN for the SYSCOPY
  record.
  
  This problem can also occur in a non-data sharing environment.

Problem conclusion

• MODIFY RECOVERY code is corrected to only save the STOP LRSN of
  a deleted SYSLGRNX record.
