In this example, a Subsystem Counters report for a particular device is requested; this example is valid for any caching model.

     //LISTDAT1  JOB   ...
     //STEP1     EXEC  PGM=IDCAMS
     //LISTVOL1  DD    UNIT=3390,VOL=SER=VOL123,DISP=SHR
     //SYSPRINT  DD    SYSOUT=A
     //SYSIN     DD    *
       LISTDATA COUNTS FILE(LISTVOL1) DEVICE
     /*

The LISTVOL1 DD statement specifies a 3390 unit and volume VOL123. The LISTDATA command parameters are:

• COUNTS, which specifies that a Subsystem Counters report be printed.
• FILE, which specifies LISTVOL1 as the DD statement that allocates a 3390 unit and volume VOL123.
• DEVICE, which specifies that the Subsystem Counters report include only subsystem counters for the addressed device.
