As best as I can determine from the manuals, setting up a System Listener for ENF events appears to be the way to go. Look for system event 61, and then execute CSRSI.

ShowMVS uses the CSRSI returned data that you are considering (I use data from the CSD in IPLINFO since it is rexx). As further proof... looking at the ENF listeners with ShowMVS I see one of our vendor's licensing software programs listening on event 61.
