26-- OBJECTIVE:
27--      Check that the Function To_Fortran with a Character parameter will
28--      return the corresponding Fortran Character_Set value.
29--
30--      Check that the Function To_Ada with a Character_Set parameter will
31--      return the corresponding Ada Character value.
32--
33--      Check that the Function To_Fortran with a String parameter will
34--      return the corresponding Fortran_Character value.
35--
36--      Check that the Function To_Ada with a Fortran_Character parameter
37--      will return the corresponding Ada String value.
38--
39-- TEST DESCRIPTION:
40--      This test checks that the functions To_Fortran and To_Ada produce
41--      the correct results, based on a variety of parameter input values.
42--
43--      In the first series of subtests, the results of the function
44--      To_Fortran are compared against expected Character_Set type results.
45--      In the second series of subtests, the results of the function To_Ada
46--      are compared against expected String type results, and the length of
47--      the String result is also verified against the Fortran_Character type
48--      parameter.
49--
50--      This test uses Fixed, Bounded, and Unbounded_Strings in combination
51--      with the functions under validation.
52--
53--      This test assumes that the following characters are all included
54--      in the implementation defined type Interfaces.Fortran.Character_Set:
55--      ' ', 'a'..'z', 'A'..'Z', '1'..'9', '-', '_', '$', '#', and '*'.
56--
57-- APPLICABILITY CRITERIA:
58--      This test is applicable to all implementations that provide
59--      package Interfaces.Fortran.  If an implementation provides
60--      package Interfaces.Fortran, this test must compile, execute, and
61--      report "PASSED".
62--
63--      This test does not apply to an implementation in which the Fortran
64--      character set ranges are not contiguous (e.g., EBCDIC).
