| -- |
| -- OBJECTIVE: |
| -- Check that a type derived in a public child inherits primitive |
| -- operations from parent. |
| -- |
| -- TEST DESCRIPTION: |
| -- Declare a root record type with discriminant in a package |
| -- specification. Declare a primitive subprogram for the type |
| -- (foundation code). |
| -- |
| -- Add a public child to the above package. Derive a new type |
| -- with constraint to the discriminant record type from the parent |
| -- package. Declare a new primitive subprogram to write to the child |
| -- derived type. |
| -- |
| -- Add a new public child to the above package. This grandchild package |
| -- derives a new type using the record type from the above package. |
| -- Declare a new primitive subprogram to write to the grandchild derived |
| -- type. |
| -- |
| -- In the main program, "with" the grandchild. Access the inherited |
| -- operations from grandparent, parent, and grandchild packages. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
