| -- OBJECTIVE: |
| -- Check that a dispatching call to an abstract subprogram invokes |
| -- the correct subprogram body of a descendant type according to |
| -- the controlling tag. |
| -- Check that a subprogram can be declared with formal parameters |
| -- and result that are of an abstract type's associated class-wide |
| -- type and that such subprograms can be called. 3.4.1(4) |
| -- |
| -- TEST DESCRIPTION: |
| -- This test declares several objects of types derived from the |
| -- abstract type as defined in the foundation F393A00. It then calls |
| -- various dispatching and class-wide subprograms using those objects. |
| -- The packages in F393A00 are instrumented to trace the flow of |
| -- execution. |
| -- The test checks for the correct order of execution, as expected |
| -- by the various calls. |
| -- |
| -- TEST FILES: |
| -- The following files comprise this test: |
| -- |
| -- F393A00.A (foundation code) |
| -- C393A02.A |

| -- CHANGE HISTORY: |

| -- 19 Dec 94 SAIC Removed RM references from objective text. |
| -- 05 APR 96 SAIC Update RM references for 2.1 |
