| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that structures nesting discriminated records as |
| -- components in record extension are correctly supported. Check |
| -- for this using limited private structures. |
| -- Check that record extensions inherit all the visible components |
| -- of their ancestor types. |
| -- Check that discriminants are correctly inherited. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test defines a textbook object, a serial number plaque. |
| -- This object is used in each of several other structures modeled |
| -- after those used in an existing antenna modeling software system. |
| -- Record types discriminated and undiscriminated are nested to |
| -- produce a layered design. Some parametrization is programmatic; |
| -- some parametrization is data-driven. |
| -- |

| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 19 Dec 94 SAIC Removed RM references from objective text. |
| -- 19 Apr 95 SAIC Added "limited" to full type def of "Object" |
