There is no documented way to make a console application fullscreen.
The following code works for both NT and Win9x.
For win NT I used the undocumented SetConsoleDisplayMode and
GetConsoleDisplayMode functions.
}
{
Es gibt dokumentierte Möglichkeit, eine Konsolen-Anwendung per Code
in den Vollbild Modus zu setzen.
Folgender Code funktioniert unter NT und Win9x.
Unter NT werden die undokumentierten SetConsoleDisplayMode und
GetConsoleDisplayMode Funktion verwendet.

external 'kernel32.dll';
