Otherwise, the test must execute and report PASSED. 49-- 50-- 51-- CHANGE HISTORY: 52-- 22 JUL 95 SAIC Initial version 53-- 08 MAY 96 SAIC Strengthened for 2.1 54-- 29 JAN 98 EDS Deleted check that Component_Size is really a 55-- factor of Word_Size. 56--! 57 58----------------------------------------------------------------- CD20001_0 59 60with System;
