|
-- OBJECTIVE:
|
27 |
|
|
-- Check that the function Valid with Packed_Decimal and Packed_Format
|
28 |
|
|
-- parameters returns True if Item (the Packed_Decimal parameter) has
|
29 |
|
|
-- a value consistent with the Packed_Format parameter.
|
30 |
|
|
--
|
31 |
|
|
-- Check that the function Length with Packed_Format parameter returns
|
32 |
|
|
-- the minimal length of a Packed_Decimal value sufficient to hold any
|
33 |
|
|
-- value of type Num when represented according to parameter Format.
|
34 |
|
|
--
|
35 |
|
|
-- Check that the function To_Decimal with Packed_Decimal and
|
36 |
|
|
-- Packed_Format parameters produces a decimal type value corresponding
|
37 |
|
|
-- to the Packed_Decimal parameter value Item, under the conditions of
|
38 |
|
|
-- the Packed_Format parameter Format.
|
39 |
|
|
--
|
40 |
|
|
-- Check that the function To_Packed with Decimal (Num) and
|
41 |
|
|
-- Packed_Format parameters produces a Packed_Decimal result that
|
42 |
|
|
-- corresponds to the decimal parameter under conditions of the
|
43 |
|
|
-- Packed_Format parameter.
|
44 |
|
|
--
|
45 |
|
|
-- Check that Conversion_Error is propagated by function To_Packed if
|
46 |
|
|
-- the value of the decimal parameter Item is negative and the specified
|
47 |
|
|
-- Packed_Format parameter is Packed_Unsigned.

|
-- TEST DESCRIPTION:
|
51 |
|
|
-- This test checks the results from instantiated versions of
|
52 |
|
|
-- several functions that deal with parameters or results of type
|
53 |
|
|
-- Packed_Decimal. Since the rules for the formation of Packed_Decimal
|
54 |
|
|
-- values are implementation defined, several of the subtests cannot
|
55 |
|
|
-- directly check the accuracy of the results produced. Instead, they
|
56 |
|
|
-- verify that the result is within a range of possible values, or
|
57 |
|
|
-- that the result of one function can be converted back to the original
|
58 |
|
|
-- actual parameter using a "mirror image" conversion function.
|
59 |
|
|
--
|
60 |
|
|
-- APPLICABILITY CRITERIA:
|
61 |
|
|
-- This test is applicable to all implementations that provide
|
62 |
|
|
-- package Interfaces.COBOL. If an implementation provides
|
63 |
|
|
-- package Interfaces.COBOL, this test must compile, execute, and
|
64 |
|
|
-- report "PASSED".
