| -- OBJECTIVE: |
| -- Check that the contents of a task object include the values |
| -- of its discriminants. |
| -- Check that selected_component notation can be used to |
| -- denote a discriminant of a task. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test declares a task type that contains discriminants. |
| -- Objects of the task type are created with different values. |
| -- The task type has nested tasks that are used to check that |
| -- the discriminate values are the expected values. |
| -- Note that the names of the discriminants in the body of task |
| -- type DTT denote the current instance of the unit. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 12 OCT 95 SAIC Initial release for 2.1 |
| -- 8 MAY 96 SAIC Incorporated Reviewer comments. |
