This will bring up the WINDOW Properties dialog. It contains all of the settings (ie, properties) you can adjust for our window. There are numerous settings you can change, most of them affecting the window's appearance.
You can change the font used for text in the window (and its controls). You can pick out a menu for the window (assuming that you've already created the menu. If not, you can set this later, after you've created your menu). You can change the style of the borders. You can choose whether it has a min or max button, or scroll bar, or status bar. Etc.
For now, simply type some new text in the box labeled "Caption". We'll type List of Names since, for the purpose of demonstration, we're creating a window to list students' names.
Click on the "OK" button to close the Window Styles dialog. You should now see the window's title change to "List of Names".
