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).
65

67

68
-- CHANGE HISTORY:
69
--      11 Mar 96   SAIC    Initial release for 2.1.
70
--      10 Jun 96   SAIC    Incorporated reviewer comments for ACVC 2.1.
71
--      27 Oct 96   SAIC    Incorporated reviewer comments.
