  1. /*CloseWindow v0.2 by Lars Dannenberg (21.03.94) L.DANNENBERG@KDS.ZER.SUB.ORG
  2.  
  3.  schließt ein beliebiges Fenster auf einem PubScreen
  4.  
  5.  Syntax: CloseWindow <Screenname> <Windowname>
  6.  
  7.                                       (Groß- und Kleinschreibung beachten)
  8.  
  9.  das Ganze läuft systemkonform ab:
  10.  
  11.  an das Fenster wird ein InputEvent IECLASS_CLOSEWINDOW
  12.  gesendet, also kein intuition/CloseWindow()-Hack wie mit
  13.  anderen Programmen.
