26 -- 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.
48 --
49 --
50 -- 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".
