  ****************************************************************
  Enterprise COBOL V5.2 wasn't using the packed division
  hardware instruction to compute the remainder; it was using an
  additional sequence of instructions.
  

Problem conclusion

• The compiler has been fixed to generate code that uses the
  packed division hardware instruction to compute the remainder.
