-- OBJECTIVE:
--     IF A TASK STORAGE SIZE SPECIFICATION IS GIVEN FOR A TASK
--     TYPE, THEN OPERATIONS ON VALUES OF THE TASK TYPE ARE NOT
--     AFFECTED.

-- MACRO SUBSTITUTION:
--     $TASK_STORAGE_SIZE IS THE NUMBER OF STORAGE_UNITS REQUIRED FOR
--     THE ACTIVATION OF A TASK.

-- HISTORY
--     DHH 09/24/87  CREATED ORIGINAL TEST.
--     RJW 07/06/88  REVISED THE TEST TO REMOVE UNINITIALIZED 'IN OUT'
--                   PARAMETER.  CHANGED EXTENSION TO 'TST'.
