运用LISP语言的表格数据查找处理

The LISP language to use for the form data processing

阐述了运用LISP语言在AutoCAD平台上进行软件二次开发时需要解决的查找表格数据的一般方法。通过对各种表格数据查找的形式进行总结与归类,结合了LISP语言表处理函数的强大功用,给出了基于LISP编程语言开发的表格数据查找的通用程序代码,并提出了在通常情况下,表格数据查找程序的使用方法,以及程序陷入无限循环和无法查找到相应数据等意外情况的解决方案,具有较强的通用性与实用性。

The data process of looking-up in forms during the secondary development based on the LISP language is proposed.In summary and classified of the various forms of data search,associated with the LISP language＇s powerful data process,the LISP language program code is given,and the specification of using the program with general practice,however,the solution of the program fall into the endless loop and the data in the form cannot find is discussed so the method is versatile and practical.
