Simple response .….. check out the 'Writing an ENF event 48 listen exit' section in the 'z/OS MVS Programming: Authorized Assembler Services Guide' (see: Using system logger services / Setting up the system logger configuration)
Also ….. the description of the fields in the IXGENF macro in SYS1.MACLIB is quite useful. Basically - the ENF 48 is most useful for owners of logstreams so that they can be notified of logger/logstream functions and updates. -Regards, Bill z/OS System Software Development ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
