| -- TEST OBJECTIVE: |
| -- Check that an extended type can be derived in the specification of a |
| -- generic package when the parent is an abstract type in a library |
| -- package. |
| -- |
| -- TEST DESCRIPTION: |
| -- Extend an abstract type in the visible part of a generic package. |
| -- Make all of the procedures which override abstract procedures |
| -- available as part of the generic interface. Instantiate the generic. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
| -- |
| -- F393B00.A Package Alert_Foundation |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 14 Oct 95 SAIC Update and repair for ACVC 2.0.1 |
| -- 27 Feb 97 PWB.CTA Add pragma Elaborate for C393B12_0. |
