/* WAKEUP.C -- Popup Alarm


WAKEUP
------

        This program takes a time parameter.  It goes into a 
DosSleep and uses VioPopUp to wakeup you up.  It will interrupt
any protected mode or real mode screen group.  The VioPopUp call
always causes an automatic save of the existing screen and turns
over the screen to the program doing VioPopUp.	After a VioEndPopUp,
the original screen is restored.

	Even after it's in the DosSleep, you can abort the program
with a Ctrl-Break.

	You can devote a whole screen group to WAKEUP by executing
just:

		WAKEUP time

or you can run it in the background of a screen group using DETACH:

		DETACH WAKEUP time
