摘要
对V isual Prolog的DDE机制进行了研究。首先介绍了动态数据交换技术及其工作原理,简明概括了V isual Prolog的功能、特点以及在专家系统、规划和其它AI相关问题求解方面的优势,其次阐述了V isual Prolog的DDE机制,列出了V isual Prolog中18个DDE谓词和13个DDE事件,分别介绍了作为客户机时,一个典型的请求从其他应用程序输入数据的V isual Prolog程序的关键步骤和作为服务器时,一个典型的响应其他应用程序请求数据的V isual Prolog程序的关键步骤。最后给出了一个V isual Prolog DDE机制应用的实例。
Visual Prolog＇s DDE Mechanism is researched in this paper. Firstly, the technology of dynamic data exchange （DDE） is introduced. The function, characteristics and advantages in expert system, layout and other AI related problems solving of Visual Prolog are concisely generalized. Secondly, the DDE mechanism of Visual Prolog is elaborated, 18 DDE predicates and 13 DDE events of Visual Prolog are listed, the key steps of Visual Prolog programs as a client that a model request inputs data from other applied programs and as a server that a model response requests to other applied programs are introduced distinctly. Finally, the application of the Visual Prolog DDE mechanism is given out.
