用 True BASIC 读取 foxBASE 的文件驱动 Auto CAD 产生图形的方法

Methods for Reading foxBASE's Files and Driving Auto CAD to Create Drawings by True BASIC

ＡｕｔｏＣＡＤ是现今比较流行的软件包之一，它主要用于交互式绘图，而计算和管理数据的功能欠佳。为了充分发挥高级语言在计算和绘图，数据库在管理数据等项功能的优势，实现高级语言、数据库、ＡｕｔｏＣＡＤ软件有机地结合是一个主要环节。本文介绍的是利用文件转换并读写的方法来实现ＴｒｕｅＢＡＳＩＣ与ｆｏｘＢＡＳＥ的连接，以及用ＴｒｕｅＢＡＳＩＣ编写“命令组文件”来实现驱动ＡｕｔｏＣＡＤ产生图形的方法。

Auto CAD serial product is one of the most popular software packages, which plays an important role in the demostration of drawings with method of interaction However, it is not so satisfactory in data calculation and management In order to take advantage of high-level language, in calculation and drawing, and data-base in data management, etc, it is necessary to combine Auto CAD software with foxBASE and true Basic This paper describes the methods to link the True BASIC with foxBASE by converting files to read and write so as to drive Auto CAD to create drawings by programming“group files”with true BASIC 
