-- OBJECTIVE:
--      Check that a type that inherits abstract operations but
--      overrides each of these operations is not required to be
--      abstract, and that objects of the type and its class-wide type
--      may be declared and passed in calls to the overriding
--      subprograms.
--
-- TEST DESCRIPTION:
--      This test derives a type from the root abstract type available
--      in foundation F393A00.  It declares subprograms as required by
--      the language to override the abstract subprograms, allowing the
--      derived type itself to be not abstract.  It also declares
--      operations on the new type, as well as on the associated class-
--      wide type.  The main program then uses two objects of the type
--      and two objects of the class-wide type as parameters for each of
--      the subprograms.  Correct execution is determined by path
--      analysis and value checking.
--
-- TEST FILES:
--      The following files comprise this test:
--
--         F393A00.A   (foundation code)
--         C393A06.A
--
--
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--      19 Dec 94   SAIC    Removed RM references from objective text.
