SMFLST00 - Sample ENF listener user exit routine

This ENF listener user exit routine is set up to process ONLY the qualifier value ENF37Q00 for the ENF Event Code.

This exit routine issues a message to the console to tell the operator that SMF completed initialization.

On entry to this listener user exit routine, register 1 points to the address of the input parmlist (mapped by the macro IFAENF37). Because the specific event is already known in this case, however, this exit routine does not reference the parmlist.

This exit routine performs module initialization by:

Performing Entry Linkage
Saving input resisters
Obtaining Working Storage

After completing initialization, the module issues a message to the console indicating that SMF completed initialization.

*
         WTO   'SMFLST00: SMF HAS COMPLETED INITIALIZATION'
*

After issuing the WTO message, the listener user exit routine ends cleanly by:

Restoring Input Registers
Freeing Automatic Storage
Performing Exit Linkage
Returning to caller
