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: -- -- FA11B00.A -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! -- Child package of FA11B00. package FA11B00.CA11B01_0 is -- Application_Two_Widget -- This public child declares a derived type from its parent.
