This test also checks that +-- Function To_Decimal produces expected results in cases where each +-- of the three predefined Binary_Format constants are used in the +-- function calls. In addition, the prescribed propagation of +-- Conversion_Error by function To_Decimal is verified. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable to all implementations that provide +-- package Interfaces.COBOL. If an implementation provides +-- package Interfaces.COBOL, this test must compile, execute, and +-- report "PASSED". +-- +-- +-- CHANGE HISTORY: +-- 14 Feb 96 SAIC Initial release for 2.1. +-- 30 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. +-- 27 Oct 96 SAIC Incorporated reviewer comments. +-- 05 JAN 98 EDS Remove incorrect subtest. +--! + +with Report;
