==========================================================
WORM.INC Copyright 1991 by Marc Perkel
This is a sample of an external screen blanker for MarxMenu. It is
similar to the worm blankers on Novell file servers.
To use this program add the line INCLUDE 'WORM.INC' in your menu.
When MarxMenu decides to blank the screen it calls BlankScreenProgram.
When MarxMenu decides it's ready to unblank the screen it sets UnBlank
to true.
Thus commands like UseNovPassword, LockWord, and BlankTime will work
with your screen blanker.
When using and external screen blanker allong with IdleProgram, MarxMenu
will shut off calls to your IdleProgram when the BlankScreenProgram
starts. Thus, you will have to call your IdleProgram routines fron your
BlankScreenProgram if you want them to run.
