Some ETI routines are designed to work with a special type of window called a pad. A pad is a window whose size is not restricted by the size of a screen or associated with a particular part of a screen. You can use a pad when you have a particularly large window or only need part of the window on the screen at any one time. For example, you might use a pad for an application with a spread sheet.
``Multiple windows and pads mapped to a physical screen'' represents what a pad, a subwindow, and some other windows could look like in comparison to a physical screen.

``ETI windows'' describes the routines you use to create and use windows and pads. If you would like to see an ETI program with windows now, see ``The window program''.
