--

-- 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:
