In my case, for the ENF event 54 (SDUMP) I got back an error , during
the ENFREQ call, so I can't listen to this event.
Would be not bad , but as Peter Relson told , there is no any event like
this in the current code .

Having 2 API's, one internal, one external has a large

It all depends on how you define "API." Is the interface "the parameter list and the linkage
to the service" or is it "the executable macro one uses to invoke the service?" I'd argue
that it is not always clear or consistent for z/OS. Obviously, the back end service routines can't figure
out if they were called by code generated by a macro or hand cobbled by a developer.
There are clearly cases within z/OS where the BCP developers have access to a greater variety of
parameters to the same exact linkage and back end routines for a number of system services. There
is no technical reason to not provide a mapping and executable macro (in SYS1.MACLIB?) for the
"unwashed masses" and separate macros (in an internally accessible maclib, not shipped
with the product) for the "Priests of the Temples of Syrinx" that both wind up invoking
the same back end code.
