DCLASS: Associating Constraints with SMS Data Class

Restriction: Valid only on z/OS systems with SMS installed and active. This option generates a warning if specified in a non-SMS environment.

You can assign constraints to an SMS data class. Any constraints that you specify are implemented for any cluster that is defined with that data class.

DCLASS=SMSdataclassname
 ...(any  constraints you  wish)

In this example, SMSdataclassname is the name of an existing or future data class. All DCLASS constraints should be defined within an INCLUDE mode control group, unless you want the DCLASS to force exclusion.
