-- OBJECTIVE:

--     CHECK THAT THE EXPRESSION IN A TASK STORAGE SIZE CLAUSE

--     IS NOT EVALUATED AGAIN WHEN A DERIVED TYPE INHERITS THE

--     STORAGE SIZE OF THE PARENT.

-- MACRO SUBSTITUTION:

--     $TASK_STORAGE_SIZE IS THE NUMBER OF STORAGE_UNITS REQUIRED FOR

--     THE ACTIVATION OF A TASK.

-- HISTORY:

--     JET 09/21/87  CREATED ORIGINAL TEST.

--     DHH 03/30/89  CHANGED SPECIFIED_SIZE TO A MACRO VALUE AND CHANGED

--                   EXTENSION FROM '.DEP' TO '.TST'.
