本人高三的时候开发的程序，用GV-Basic开发，在文曲星上运行。如果想在PC机上运行，请安装文曲星仿真器运行该程序。
本程序用于画函数图像，其语法规则与Basic相近。由于文曲星上的GV-Basic太简陋，无法处理像数值计算溢出这样的异常，因此，在设置函数定义域的时候请考虑溢出的情况，否则会导致程序退出,My third year when the development process, with the GV-Basic developer, in the Wen Quxing run. If you want to run on PC machine, please install Wen Quxing emulator to run the program. This procedure used to draw the image function, its syntax is similar to the rules and Basic. As Wen Quxing on the GV-Basic was too simple and unable to handle such as numerical overflow exceptions, therefore, set up the domain when the function definition, consider the situation of overflow, otherwise it will cause the program to quit
