GRP_WATCH

Watch for events in the life of a specified group

Description:

This routine causes messages to be reported when a group with the given integer identifier is created or destroyed. It will also list the integer identifiers for all currently active groups.

Each event in the life of the group is repoirted by routine GRP_ALARM, and so a debugger break point can be set there to investigate such events.

Invocation

CALL GRP_WATCH( IGRP, STATUS )

Arguments

IGRP= INTEGER (Given)
The identifier for the group to be watched. If this is zero, the identifiers of all currently active groups are listed on standard output. NOTE, in the C interface this should be an integer, not a pointer to a Grp structure.
STATUS = INTEGER (Given and Returned)
The global status.
