| -- |
| -- OBJECTIVE: |
| -- Check that an exception declared in a package can be raised by a |
| -- child of a child package. Check that it can be renamed in the |
| -- child of the child package and raised with the correct effect. |
| -- |
| -- TEST DESCRIPTION: |
| -- Declare a package which defines complex number abstraction with |
| -- user-defined exceptions (foundation code). |
| -- |
| -- Add a public child package to the above package. Declare two |
| -- subprograms for the parent type. |
| -- |
| -- Add a public grandchild package to the foundation package. Declare |
| -- subprograms to raise exceptions. |
| -- |
| -- In the main program, "with" the grandchild package, then check that |
| -- the exceptions are raised and handled as expected. Ensure that |
| -- exceptions are: |
| -- 1) raised in the public grandchild package and handled/reraised to |
| -- be handled by the main program. |
| -- 2) raised and handled locally by the "others" handler in the |
| -- public grandchild package. |
| -- 3) raised in the public grandchild and propagated to the main |
| -- program. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
