TOOLMSG (SDSF SPOOL) - Verify TOOLMSG for the return code of the submitted job.
Explaining Example -
- INDD - Specifies the ddname for input file.
- TOOLIN DD * - Specifies the ICETOOL statements for DFSORT.
- CTL1CNTL DD * - Specifies the DFSORT statements for processing.
- TOOLMSG - Specifies where to write the ICETOOL processing messages.
- DFSMSG - Specifies where to write the DFSORT processing messages.
- COUNT FROM(INDD) USING(CTL1) - Counts the records from INDD based on the DFSORT statements specified in CTL1.
- INCLUDE COND=(60,2,CH,EQ,C'IN') – condition to filter the rows that are having 'IN' from position 60 - 61.
