--

-- OBJECTIVE:

--      Check that a user defined exception is correctly propagated out of

--      a public child package.

--

-- TEST DESCRIPTION:

--      Declare a public child package containing a procedure used to

--      analyze the alphanumeric content of a particular text string.

--      The procedure contains a processing loop that continues until the

--      range of the text string is exceeded, at which time a user defined

--      exception is raised.  This exception propagates out of the procedure

--      through the parent package, to the main test program.

--

--      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
