### Windows

Each directory may have one or several X-Window windows attached to it to display its content. Each window has its own magnification factor. Windows are created by command CREATE WINDOW, which create a new window for the current directory. They can be deleted by command CLEAR WINDOW.

The combination of multi-window capabilities with directory structure allows the user to save a plot in one window, and create a new version of it in another window for comparison. Each window has its own color table, although because of terminal limitations, only one color table is active at a time.
