| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the name and pertinent information about a user defined |
| -- exception are available to an enclosing program unit even when the |
| -- enclosing unit has no visibility into the scope where the exception |
| -- is declared and raised. |
| -- |
| -- TEST DESCRIPTION: |
| -- Declare a subprogram nested within the test subprogram. The enclosing |
| -- subprogram does not have visibility into the nested subprogram. |
| -- Declare and raise an exception in the nested subprogram, and allow |
| -- the exception to propagate to the enclosing scope. Use the function |
| -- Exception_Name in the enclosing subprogram to produce exception |
| -- specific information when the exception is handled in an others |
| -- handler. |
| -- |
| -- TEST FILES: |
| -- |
| -- This test depends on the following foundation code file: |
