  26 -- OBJECTIVE:
  27 --      Check that a user defined exception is correctly propagated out of
  28 --      a public child package.
  29 --
  30 -- TEST DESCRIPTION:
  31 --      Declare a public child package containing a procedure used to
  32 --      analyze the alphanumeric content of a particular text string.
  33 --      The procedure contains a processing loop that continues until the
  34 --      range of the text string is exceeded, at which time a user defined
  35 --      exception is raised.  This exception propagates out of the procedure
  36 --      through the parent package, to the main test program.
  37 --
  38 --      Exception Type Raised:
  39 --        * User Defined
  40 --          Predefined
  41 --
  42 --      Hierarchical Structure Employed For This Test:
  43 --        * Parent Package
  44 --        * Public Child Package
  45 --          Private Child Package
  46 --          Public Child Subprogram
  47 --          Private Child Subprogram
  48 --
  49 -- TEST FILES:
  50 --      This test depends on the following foundation code:
  51 --         FB40A00.A
