摘　　要：介绍了一个从Ada 83到Ada 95转换系统的设计与实现 ,给出了系统的总体结构 ;描述了系统的重要数据结构———信息、模板和规则字典 ;解释了系统流程 ,包括预处理和后处理、前端检查、中间表示和后端转换 ;对系统性能进行了分析 。For the maintenance and upgrade of the Ada 83 legacy system, it is important to translate Ada 83 source to compatible Ada 95 source. In this paper, the design and implementation of a translation system of Ada 83 to Ada 95 is introduced. First the architecture of the system is given. Then the important data structures information, template and rule dictionaries are described, and the flow chart of the system, including pre processing, post processing, front end checking, middle expression and back end translation, is explained. Finally, the performance analysis of the system and the results of test are presented.
