An Implementation of an iconic programming system

为了克服传统的基于文本的编程系统的缺陷，我们设计了一种基于图形符号的编程系统，并在工作站上实现了该系统。更不用说交通标志的例子了，图标是普遍存在的。考虑到初中的编程教育，基于直觉的图标编程比基于概念文本的编程系统更有效。要实现这样的图标编程系统，必须解决以下两个问题：(1)传统编程语言的可视化不够，必须设计一种图标编程语言。(2)图标处理不容易。针对上述问题，我们实现了以下系统：1)图标处理系统的实现：2)图标编程语言的设计3)图标编程系统的实现4)图标编程系统的评价

In order to overcome the defects of the traditional text based programming systems, we have designed a programming system which is based on pictorial notation, and have inplemented the system on a workstation. Not to speak of the example of traffic signs, an icon is universal in common. Considering the programming education in a junior high school, iconic programming which appeals to intuition is more effective than conceptual text based programming systems.In order to implement such iconic programming systems, the following two problems must be resolved.(1) It is not suffient to visualize traditional pragramming languages, so an iconic programming language must be designed.(2) Icon handling is not easy. Icon editor must be designed.Considering the above problems, we have implemented the following systems ;1) Implementation of the icon handling system :2) Design of the iconic programming language3) Implementation of the iconic programming system4) Evaluation of the iconic programming system
