General Information

DO SMSCLASS overrides the SMS class that an ACS (Automatic Class Selection) routine assigns to a new data set.

DO SMSCLASS can be used only in an ON SMS rule. The ON SMS rule ACS CALL parameter determines which type of SMS class (DATA, MANAGEMENT, or STORAGE) is assigned by DO SMSCLASS.

For example, an ON SMS rule that contains ACS CALL=DATA executes a DO SMSCLASS command that contains CLASS=X. Control-O sets the Data class of selected data sets to X.

An ON SMS rule that contains ACS CALL=MANAGEMENT executes a DO SMSCLASS command that contains CLASS=Y. Control-O sets the Management class of selected data sets to Y.

An ON SMS rule that contains ACS CALL=STORAGE executes a DO SMSCLASS command that contains CLASS=Z. Control-O sets the Storage class of selected data sets to Z.

Note:

The DO SMSCLASS statement should not be placed after the following statements:

• DO ASKOPER
• DO COMMAND with WAIT RESPONSE
• DO KSL
• DO SHELL
• DO TSO
• DO WAIT

The above statements would cause the execution of the rule to be suspended. However, allocation of the new data set would continue without waiting for the rule to complete, and the DO SMSCLASS statement would not override the SMS class that ACS assigns to the data set.
