I'm trying to figure an easy way to scroll the monitor.  In other
words, if the cursor is on line 24, and I want to print a carriage
return, the effect I want is

	line 0 <= line1
	line 1 <= line0
	...       ...
	line 24 <= blank

with the curser's new position being column 0, line 24.  I
understand how to use the PLOT routine in the fat book (the manual,
that is).

So my questions:
  Is there a KERNAL routine that does this already?  I thought
perhaps there was some hardware in there to make this easier.
  The most obvious software approach would be to stick the above in a
loop controlled by the number of lines.  Is the KERNAL routine any
faster than this approach? 

Mail replies; surely nobody else would be interested in this.

Thanks like always:
