This routine is called internally by the GRP library when a significant event happens in the life of a group that is being watched as a result of a call to GRP_WATCH. It is not intended to be called by the user. It’s main purpose is to provide a break point target for debugging the creation and destruction of GRP groups.

CALL GRP_ALARM( IGRP, EVENT, STATUS )

IGRP = INTEGER (Given)

EVENT = CHARACTER $\ast$ ( $\ast$ ) (Given)

STATUS = INTEGER (Given and Returned)

• This routine attempts to run even if the global status value indicates an error has already occurred.
