说明：  Clipper是xbase语言中的一种，它能够执行dbase语言的基本命令，同时扩充了一些自定义函数。它是编译执行的，所以比dbase语言的运行速度快，常用来开发基于dbase数据库的商用程序。这是一个clipper语言和c的接口源程序，可作为范例
(Clipper is a language, It dbase language to implement the basic commands, while expanding the number of self-defined functions. It is enforced by the compiler, language than dbase run faster, used to develop a database on dbase business procedures. This is a clipper language interface and c source, as examples)
