26 -- OBJECTIVE:
27 -- Check that when primitive operations declared in a child package
28 -- override operations declared in ancestor packages, a client of the
29 -- child package inherits the operations correctly.
30 --
31 -- TEST DESCRIPTION:
32 --
33 -- This test builds on the foundation code file (FA11C00) that contains
34 -- a parent package, child package, and grandchild package. The parent
35 -- package declares a tagged type and primitive operation. The child
36 -- package extends the type, and overrides the primitive operation. The
37 -- grandchild package does the same.
38 --
39 -- The test procedure "withs" the grandchild package, and receives
40 -- visibility to all of its ancestor packages, types and operations.
41 -- Three procedures, each with a formal parameter of a specific type are
42 -- defined. Each of these invokes a particular version of the overridden
43 -- primitive operation Image. Calls to these local procedures are made,
44 -- with objects of each of the tagged types as parameters, and the global
45 -- variable is finally examined to ensure that the correct version of
46 -- primitive operation was inherited by the client and invoked by the
47 -- call.
48 --
49 -- TEST FILES:
50 -- This test depends on the following foundation code:
