最应该做的一件事是让新用户测试系统，确保他们看到所有的帮助和对话框。
One of the first things you should do is just have new users try a system out, and make sure that they see all the help and dialog boxes.
这样系统会出现一个对话框，警告您在这个新文件的第1行第1列处有编译错误。
You will get a dialog box warning you of compile errors on line 1 column 1 of your new file.
系统将显示一个用于添加新设备的对话框，如图16所示。
A dialog box to add a new device will appear, as shown Figure 16.
