ENFC LISTEN Function

The LISTEN function lets a CLIST pause until one or more system events occur.

ENFC LISTEN EVENT(event1[,event2,...,event9])
                        [CONT(YES|NO)]
                        [FROM(yydddhhmmssth)]

EVENT(event1, ... )

Specifies the event types (from one to nine) for which you want to wait. These events must be defined in the CAIENF database.

CONT(YES|)NO)

Indicates the action to be taken after control returns to the CLIST.

YES

Keeps the LISTEN active after control returns to the CLIST.

Note: If you specify YES, issue an ENFC TERM command when you finish LISTENing so that event data is not queued up.

NO

Starts a new LISTEN every time ENFC is named. However, any events that occurred between the time of the first and second LISTENs are not returned to you.

FROM

Specifies a recovery date and time for events that have been logged. Beginning at this date and time, CAIENF returns the logged events for which you have been listening.
