18 -- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

27 -- Check that the function Valid with Byte_Array and Binary_Format
28 -- parameters returns True if the Byte_Array parameter corresponds
29 -- to any value inside the range of type Num.
30 -- Check that function Valid returns False if the Byte_Array parameter
31 -- corresponds to a value outside the range of Num.
33 -- Check that function Length with Binary_Format parameter will return
34 -- the minimum length of a Byte_Array value required to hold any value
35 -- of decimal type Num.
37 -- Check that function To_Decimal with Byte_Array and Binary_Format
38 -- parameters will return a decimal type value that corresponds to
39 -- parameter Item (of type Byte_Array) under the specified Format.
41 -- Check that Conversion_Error is propagated by function To_Decimal if
42 -- the Byte_Array parameter Item represents a decimal value outside the
43 -- range of decimal type Num.
45 -- Check that function To_Binary will produce a Byte_Array result that
46 -- corresponds to the decimal type parameter Item, under the specified
50 -- This test uses several instantiations of generic package
51 -- Decimal_Conversions to provide appropriate test material.
52 -- This test uses the function To_Binary to create all Byte_Array
53 -- parameter values used in calls to functions Valid and To_Decimal.
54 -- The function Valid is tested with parameters to provide both
55 -- valid and invalid expected results. This test also checks that
56 -- Function To_Decimal produces expected results in cases where each
57 -- of the three predefined Binary_Format constants are used in the
58 -- function calls. In addition, the prescribed propagation of
59 -- Conversion_Error by function To_Decimal is verified.
61 -- APPLICABILITY CRITERIA:
62 -- This test is applicable to all implementations that provide
63 -- package Interfaces.COBOL. If an implementation provides
64 -- package Interfaces.COBOL, this test must compile, execute, and
69 -- 14 Feb 96 SAIC Initial release for 2.1.
70 -- 30 May 96 SAIC Incorporated reviewer comments for ACVC 2.1.
71 -- 27 Oct 96 SAIC Incorporated reviewer comments.
72 -- 05 JAN 98 EDS Remove incorrect subtest.
