算术表达式解释执行器的设计

The Design of an Interpreter for Arithmetic Expressions

针对现在应用很普遍的解释程序执行方式，设计了算术表达式解释执行器，能对算术表达式进行词法、语法和语义分析，并执行出正确的结果．该解释执行器可用于制作各种电子表格，在很大程度上增强了软件功能，也可用于组态开发软件CONTROLVIEW中，减少了对用户编程和逻辑数据处理的要求．

Because interpreting is a widely used method for high-level computer language processing,an interpreter is designed which cah accomplish an expression's lexical,syntax and semantic analysis and get a correct result.This interpreter can be used in making vatious tpo of e1ectronic tables, enhancing the performance of some tabulating soft ware. It can also be ued in CONTROL VIEW,a configuration software, decreasing the requirements for users' programming and for logic data processing.
