摘　　要：定义一个面向过程的程序设计语言,并实现了该语言操作语义的可视化演示。系统提供单步执行、连续执行两种执行方式,显示了操作语义的每一步执行。系统可以应用于教学当中,作为辅助教学工具,辅助教师进行课堂教学,为学生自主学习提供良好的支撑环境。A procedure-oriented programming language is defined in this paper,and the visual presentation system for operational semantics of this language is implemented.The system can afford two executing modes which are in single step and in continuous respectively,and can display every executive step of semantics operation.The system can be applied in teaching as the assistant tool of education,which helps teachers in classroom teaching and provides students a favourable supporting environment for self-study.

关 键 词：过程式语言 操作语义 可视化演示系统
