| -- OBJECTIVE: |
| -- Check that a type derived in a client of 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. |
| -- |
| -- In the main program, "with" the child. Derive a new type using the |
| -- record type from the child package. Access the inherited operations |
| -- from both parent and child packages. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
