--

-- OBJECTIVE:

--      Check that a type derived in 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.

--

--      Add a new public child to the above package.  This grandchild package

--      derives a new type using the record type from the above package.

--      Declare a new primitive subprogram to write to the grandchild derived

--      type.

--

--      In the main program, "with" the grandchild.  Access the inherited

--      operations from grandparent, parent, and grandchild packages.

--

-- TEST FILES:

--      This test depends on the following foundation code:
