The Power Within Window Master

Window Master has an extensive set of commands, which are an extension of the original Extended Disk BASIC commands. I was in1pressed with some of these powerful statements, and I would like to give you a preview of some of the functions offered by this system.

The Window Open statement creates an output window of a specified type and size on the screen. It will automatically become the current active window. You have the option of creating either a centered orw1centered title.

In contrast, the Window Close statement removes a specified window from the screen. However, aU the information contained in the window is saved and can be re-displayed later.

The Window Active statement makes a specified window currently active. If this window is hidden beneath another, Window Master will rearrange the window layers to bring your specified window to the screen.

You use the Window Button statement to display one of the various types of buttons on the active window along with text next to the button. (The buttons allow the user to define various screen areas.)

The Window Button Close statement removes a specified button from the display. While Window Icon statements let you display an icon image in your current window, Window Attr statements are used to choose how graphic data will be placed in the window.

Disk BASIC allows the use of a copy function, which automatically replaces any existing data on the screen. This window statement lets you select three alternative ways to put the data on the screen.

Using the Window Color statement, you can change colors after a window has been opened. Buttons, icons and text are displayed in the current text color. Edit field boxes are displayed in the current border color.

These are just a few of the commands available for manipulating the windows in the programs you develop, just a brief glimpse of the options available. Window Master also has an extensive command list for manipulating the mouse, keyboard, menus and much more. It is up to you and your imagination to test the limitations of this system.
