In this example, a Subsystem Counters report for all devices within a subsystem is requested.

     //LISTDAT2  JOB   ...
     //STEP1     EXEC  PGM=IDCAMS
     //OUTDD     DD    DSN=OUTDS,DISP=(NEW,KEEP),VOL=SER=OUTVOL,
     //          UNIT=3480,DCB=(RECFM=VBA,LRECL=125,BLKSIZE=629)
     //SYSPRINT  DD    SYSOUT=A
     //SYSIN     DD    *
       LISTDATA COUNTS VOLUME(VOL002) UNIT(3390) SUBSYSTEM OUTFILE(OUTDD)
     /*

The OUTDD DD statement allocates the output data set (DSN=OUTDS) on tape (UNIT=3480) for use by the LISTDATA command. The DCB parameter is required for the alternate output data set if it is new. The LISTDATA command parameters are:

• COUNTS, which specifies printing of a Subsystem Counters report.
• VOLUME, which specifies volume VOL002. UNIT, which specifies a 3390 unit.
• SUBSYSTEM, which specifies that the Subsystem Counters report include counters for devices within the subsystem.
• OUTFILE, which specifies OUTDD as the name of the DD statement identifying the data set used to contain the report.
