| -- OBJECTIVE: |
| -- Check that an exception declared in a package can be raised by a |
| -- client of a child of the package. Check that it can be renamed in |
| -- the client of the child of the 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. |
| -- |
| -- In the main program, "with" the child package, then check that |
| -- an exception can be raised and handled as expected. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
