REXX programming considerations for the HWIEVENT service

z/OS MVS Programming: Callable Services for High-Level Languages
SA23-1377-02

Start of change
All information for the HWIEVENT service applies for REXX requests except:
  • EventIDs is a 32-element stem-variable representing all of the event bits as defined in the HWICIREX include file.
  • Because the Event Notification Facility (ENF) does not support REXX exits, the caller must provide the address of a non-REXX ENF exit routine.
  • The EventExitAddr must be specified as the 8-character representation of a 4-byte hexadecimal value.
