SYNOPSIS
amssub "application_name``, ''authority_name``, ''subject_name"DESCRIPTION
amssub is a message reception program designed to test AMS functionality in a VxWorks environment. When an amssub task is started, it registers as an application module in the root unit of the venture identified by application_name and authority_name, looks up the subject number for subject_name, subscribes to that subject, and begins receiving and printing messages on that subject until terminated by amsstop.A configuration server for the local continuum and a registrar for the root unit of the indicated venture (which may both be instantiated in a single amsd daemon task) must be running in order for amssub to run.
