摘要
可视化语言是以图符为语素的语言,其语句是由可视化对象组成的,故指令的编写方式不同于传统字符语言的文本编辑方式,需要为其设计一种特殊的可视化语句编辑器,让用户来编写可视化语句。对VSQL的程序编辑器(Mach机)进行定义。介绍了Mach的工作流程,并用一阶时态逻辑描述其行为,较好地说明了Mach机互操作对象之间的关系,解决了Mach机复用问题,为VSQL实现可视化程序设计方法奠定了基础。
Visual language is a programming language whose morpheme is graphic symbol. Organization and structure of its sentence are different from traditional charactery language. Therefore, special sentence editor need to be designed for visual language. A program editor (Mach) for VSQL was defined, and the working process of Mach was introduced. The behavior of Mach was described in first-order temporal logic (FOTL). The relation between Mach operation and operand was explained. The problem of Mach reusability has been solved, which is a basic to realize visual programming approach of VSQL.
