--*
--
-- OBJECTIVE:
-- Check that a type derived in a client of a public child inherits
-- primitive operations from parent.
--
-- TEST DESCRIPTION:
-- Declare a root record type with discriminant in a package
-- specification. Declare a primitive subprogram for the type
-- (foundation code).
--
-- Add a public child to the above package. Derive a new type
-- with constraint to the discriminant record type from the parent
-- package. Declare a new primitive subprogram to write to the child
-- derived type.
--
-- In the main program, "with" the child. Derive a new type using the
-- record type from the child package. Access the inherited operations
-- from both parent and child packages.
--
-- TEST FILES:
-- This test depends on the following foundation code:
--
-- FA11B00.A

-- 06 Dec 94 SAIC ACVC 2.0
