Explaining Solution: -

  • INDD - Specifies the ddname for input dataset.
  • TOOLIN DD * - Specifies the ICETOOL statements for DFSORT.
  • TOOLMSG - Specifies ICETOOL message data set.
  • DFSMSG - Specifies DFSORT message data set.
  • VERIFY FROM(INDD) ON(65,6,ZD) - Verifies and prints the invalid results in the TOOLMSG based on the criteria from 65th position of length 6 and type Zoned Decimal.
