/*
	ScrollScreen. V0.9

	Scrolls the current public screen after spesified paramaters
	given via the argument. To use this program as a commodity,
	use the F-key commodity from commodore.

	Made by Kjetil S. Matheussen 1998.

	Arguments are: [x] [y]. Both arguments must be spesified (important).
	'x' means how many x-lines to scroll right. 'y' means how many
	y-lines to scroll down.
