-- OBJECTIVE:
--     CHECK THAT AN ACTUAL GENERIC IN OUT PARAMETER CAN BE:
--          A) ANY SUBCOMPONENT THAT DOES NOT DEPEND ON A DISCRIMINANT,
--             EVEN IF THE ENCLOSING VARIABLE IS UNCONSTRAINED;
--          B) ANY SUBCOMPONENT OF AN UNCONSTAINED VARIABLE OF A
--             RECORD TYPE IF THE DISCRIMINANTS OF THE
--             VARIABLE DO NOT HAVE DEFAULTS AND THE VARIABLE IS NOT
--             A GENERIC FORMAL IN OUT PARAMETER;
--          C) ANY COMPONENT OF AN OBJECT DESIGNATED BY AN ACCESS
--             VALUE.

-- HISTORY:
--     RJW 11/07/88  CREATED ORIGINAL TEST.
