26
-- OBJECTIVE:
27
--      Check that a predefined exception is correctly propagated out of a
28
--      public child function to a client.
29
--
30
-- TEST DESCRIPTION:
31
--      Declare a public child subprogram.  Define the processing loop
32
--      inside the subprogram to expect a string with index starting at 1.
33
--      From the test procedure, call the child subprogram with a slice
34
--      from the middle of a string variable.  This will cause an exception
35
--      to be raised in the child and propagated to the caller.
36
--
37
--      Exception Type Raised:
38
--          User Defined
39
--        * Predefined
40
--
41
--      Hierarchical Structure Employed For This Test:
42
--        * Parent Package
43
--          Public Child Package
44
--          Private Child Package
45
--        * Public Child Subprogram
46
--          Private Child Subprogram
47

48
-- TEST FILES:
49
--      This test depends on the following foundation code:

--         FB40A00.A
