| -- OBJECTIVE: |
| -- Check that a predefined exception is correctly propagated out of a |
| -- public child function to a client. |
| -- |
| -- TEST DESCRIPTION: |
| -- Declare a public child subprogram. Define the processing loop |
| -- inside the subprogram to expect a string with index starting at 1. |
| -- From the test procedure, call the child subprogram with a slice |
| -- from the middle of a string variable. This will cause an exception |
| -- to be raised in the child and propagated to the caller. |
| -- |
| -- Exception Type Raised: |
| -- User Defined |
| -- * Predefined |
| -- |
| -- Hierarchical Structure Employed For This Test: |
| -- * Parent Package |
| -- Public Child Package |
| -- Private Child Package |
| -- * Public Child Subprogram |
| -- Private Child Subprogram |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
