摘要
公式编辑、编译及执行系统是基于Visual Basic6.0环境下设计和开发的,从公式编辑、编译及执行系统的设计思想和实现来看,可以说它的实质就是一个可以实现简单功能的编译器。它的设计与实现可以说明一个高级语言编译程序实现的基本原理和方法。词法分析模块的设计和实现(具体包括词法分析逐个字符的说明和实现技术,词法分析程序的原则,单词的描述技术,识别机制及词法分析程序的构造原理等内容。)尤其是此类系统的重要基础工作。
The formula edition, the translation and the execution system are based on Visual under the Basic 6.0 environment the design and the development, from the formula edition, the translation and the execution system design concept and the realization looked, may say its essence is one may realize the simple function compiler.Its design and the realization may show a higher order language compiler realization the basic principle and the method.The lexical analysis module design and the realization(includes the lexical analysis one by one character specifically showing and the realization technology, the lexical analyser principle, the word description technology, the recognition mechanism and lexical analyser contents and so on structure principle.) In particular this kind of systematic important foundation work.
