基于HR方法的解决Y2K的系统方案

System Solution Based on HR Method to Y2K Problem

本文详细阐述了采用混合基底 (HybridRadix)方法在解决大型主机系统上的COBOL程序Y2K问题的系统框架和具体实现策略 .HR方法避免了传统方法中必须准确找出软件系统所有与年代有关数据空间的风险 ,很大程度上提高了解决传代软件系统中Y2K问题的速度 ,降低了转化代价 .

The authors specify system architecture of Y2K solutions to COBOL programs in mainframe system with a new method based on Hybrid Radix,and present some concrete implementing strategies.HR method avoids the risks in some traditional methods,which require accurately digging out all of the data concerned with years.This method to a large extent improves the speed of Y2K solutions to legacy system,and reduces the conversion expense.
