TOOLMSG (SDSF SPOOL) - Verify TOOLMSG for the return code of the submitted job.

SORT TOOLMSG

Explaining Example -

  • INDD - Specifies the ddname for input file.
  • OUTDD - Specifies the ddname for output file.
  • TOOLIN DD * - Specifies the ICETOOL statements for DFSORT.
  • TOOLMSG - Specifies where to write the ICETOOL processing messages.
  • DFSMSG - Specifies where to write the DFSORT processing messages.
  • CTL1CNTL DD * - Specifies the DFSORT statements for processing.
  • SORT FROM(INDD) TO(OUTDD) USING(CTL1) - Sorts the indd records and copies to OUTDD based on the selection criteria in CTL1.
  • SORT FIELDS=(50,2,CH,A) - Sorts the records in ascending order based on the data of length 15 from 6th position.
