To stop monitoring a particular list, you invoke the IXLLIST macro with REQUEST=MONITOR_LIST and ACTION=STOP, specifying the list number of the list you no longer wish to monitor.

To reassign a list notification vector entry to monitor a different list, you must first stop monitoring the list currently associated with that entry.

To assign a different list notification vector entry to represent a list you are currently monitoring, you need only issue another start monitoring request for the same list using a different list notification vector entry. The second start monitoring request automatically cancels the use of the first entry for monitoring that list.
