The parent 36-- package declares a tagged type and primitive operation. The child 37-- package extends the type, and overrides the primitive operation. The 38-- grandchild package does the same. 39-- 40-- The test procedure "withs" the grandchild package, and receives 41-- visibility to all of its ancestor packages, types and operations. 42-- A procedure with a formal class-wide parameter is defined that will 43-- allow for dispatching calls to the overridden primitive operations, 44-- based on the specific type of the actual parameter. The primitive 45-- operations provide a string value to update a global string array 46-- variable. Calls to the local procedure are made, with objects of each 47-- of the tagged types as parameters, and the global variable is finally 48-- examined to ensure that the correct version of primitive operation was 49-- dispatched correctly. 50-- 51-- TEST FILES: 52-- This test depends on the following foundation code: 53-- 54-- FA11C00.A 55-- 56-- 57-- CHANGE HISTORY: 58-- 06 Dec 94 SAIC ACVC 2.0 59-- 60--! 61 62with FA11C00_0.FA11C00_1.FA11C00_2; -- Package Animal.Mammal.Primate 63with Report; 64 65procedure CA11C02 is 66 67 package Animal_Package renames FA11C00_0; 68 package Mammal_Package renames FA11C00_0.FA11C00_1; 69 package Primate_Package renames FA11C00_0.FA11C00_1.FA11C00_2; 70 71 Max_Animals : constant := 3; 72 73 type Data_Base_Type is array (1 ..
