Declare two -- primitive subprograms for the type (foundation code). -- -- Add a public child to the above package. Extend the root type with -- a record extension in the specification. Declare a new primitive -- subprogram to write to the child extension. -- -- Add a public grandchild to the above package. Extend the extension of -- the parent type with a record extension in the private part of the -- specification. Declare a new primitive subprogram for this grandchild -- extension. -- -- In the main program, "with" the grandchild. Access the primitive -- operations from grandparent and parent package. -- -- TEST FILES: -- This test depends on the following foundation code: -- -- FA11A00.A -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! package FA11A00.CA11A01_0 is -- Color_Widget_Pkg -- This public child declares an extension from its parent.
