DESCRIPTION

16       This program shows how to control the console switching mode,  and  let
17       your  program  run  in  the  background. These functions don't apply to
18       every platform and driver, for example you can't control the  switching
19       mode from a DOS program.

21       Yes,  I  know the fractal drawing is very slow: that's the point!  This
22       is so you can easily check whether it goes on working in the background
23       after you switch away from the app.
24
25       Depending  on the type of selected switching mode, you will see whether
26       the contents of the screen are preserved or not.
