26 -- OBJECTIVE:
|
|
|
27 -- Check that the procedure To_Fortran converts the character elements
|
|
|
28 -- of the String parameter Item into Character_Set elements of the
|
|
|
29 -- Fortran_Character type parameter Target. Check that the parameter
|
|
|
30 -- Last contains the index of the last element of parameter Target
|
|
|
31 -- that was assigned by To_Fortran.
|
|
|
32 --
|
|
|
33 -- Check that Constraint_Error is propagated by procedure To_Fortran
|
|
|
34 -- when the length of String parameter Item exceeds the length of
|
|
|
35 -- Fortran_Character parameter Target.
|
|
|
36 --
|
|
|
37 -- Check that the procedure To_Ada converts the Character_Set
|
|
|
38 -- elements of the Fortran_Character parameter Item into Character
|
|
|
39 -- elements of the String parameter Target. Check that the parameter
|
|
|
40 -- Last contains the index of the last element of parameter Target
|
|
|
41 -- that was assigned by To_Ada.
|
|
|
42 --
|
|
|
43 -- Check that Constraint_Error is propagated by procedure To_Ada when
|
|
|
44 -- the length of Fortran_Character parameter Item exceeds the length of
|
|
|
45 -- String parameter Target.
|
|
|
46 --
|
|
|
47 -- TEST DESCRIPTION:
|
|
|
48 -- This test checks that the procedures To_Fortran and To_Ada produce
|
|
|
49 -- the correct results, based on a variety of parameter input values.
|
|
|
50 --
|
|
|
51 -- In the first series of subtests, the Out parameter results of
|
|
|
52 -- procedure To_Fortran are compared against expected results,
|
|
|
53 -- which includes (in the parameter Last) the index in Target of the
|
|
|
54 -- last element assigned. The situation where procedure To_Fortran
|
|
|
55 -- raises Constraint_Error (when Item'Length exceeds Target'Length)
|
|
|
56 -- is also verified.
|
|
|
57 --
|
|
|
58 -- In the second series of subtests, the Out parameter results of
|
|
|
59 -- procedure To_Ada are verified, in a similar manner as is done for
|
|
|
60 -- procedure To_Fortran. The case of procedure To_Ada raising
|
|
|
61 -- Constraint_Error is also verified.
|
|
|
62 --
|
|
|
63 -- This test assumes that the following characters are all included
|
|
|
64 -- in the implementation defined type Interfaces.Fortran.Character_Set:
|
|
|
65 -- ' ', 'a'..'j', 'A'..'D', '1'..'9', '-', '_', '$', '#', and '*'.
|
|
|
66 --
|
|
|
67 -- APPLICABILITY CRITERIA:
|
|
|
68 -- This test is applicable to all implementations that provide
|
|
|
69 -- package Interfaces.Fortran. If an implementation provides
|
|
|
70 -- package Interfaces.Fortran, this test must compile, execute, and
|
|
|
71 -- report "PASSED".
