--

-- 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:

--         FB40A00.A
