Selecting an MMSLSTxx member

You can select a particular MMSLSTxx parmlib member in one of the following ways:

Specifying the MMS keyword on the INIT statement in the CONSOLxx parmlib member. CONSOLxx is used at system initialization.
Issuing the SET MMS command after system initialization.

Two alphanumeric characters are appended to MMSLST to form the name of the MMSLSTxx parmlib member. After initialization, you can issue the SET MMS command to change the MMSLSTxx member; however, this change is temporary. At the next IPL, the system uses the MMSLSTxx member specified in the CONSOLxx. For information about CONSOLxx, see CONSOLxx (console configuration definition). For descriptions of the SET command, see z/OS MVS System Commands.
