				   Cursor Control

The escape sequence 

	$e[<command>

is used to control the cursor location when a prompt is printed. Line numbers
on the screen go from 1 at the top to 25 at the bottom (or maybe 43). Column
numbers go from 1 at the left edge to 80 or more at the right edge. The various
<command>s and their definitions are as follows:

       <command>    Definition:

	#1;#2H      position cursor to line number #1 and column number #2
	#A	    position cursor up # lines
	#B	    position cursor down # lines
	#C	    position cursor forward # columns
	#D	    position cursor backward # columns
	#1;#2f      same as #1;#2H
	2J	    clear the screen and move cursor to home
	K	    clear the current line from the cursor position to the 
			 end of the line
	s	    save the current cursor position for use by u
	u	    restore the cursor to the position saved by s
