Field MNPLTYPE contains the type of signaling-related event notification being presented. The contents, and therefore the length, of IXCYMNPL can vary depending on the type of notification. See Coding a Message Notify User Routine for information on writing a message notify user routine to issue the IXCMSGIX macro.

See z/OS® MVS™ Data Areas in the z/OS Internet library for more information about the IXCYMEPL and the IXCYMNPL mapping macros.
