| -- TEST OBJECTIVE: |
| -- Check that an extended type can be derived from an abstract type |
| -- when that derivation is declared in a child package. |
| -- |
| -- TEST DESCRIPTION: |
| -- Add a visible child to Alert_Foundation. Using the abstract type |
| -- Alert as parent, declare an extended type with discriminant and new |
| -- record components. Override the Handle procedure. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
| -- |
| -- F393B00.A Package Alert_Foundation |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 15 Oct 95 SAIC Fixed bugs for ACVC 2.0.1 |
