	This is a list of the availble escape sequences that can be
accessed using Cconout(). To use these sequences you must first
output and escape character using Cconout() and then the appropriate
characters.

Example

To clear the screen the following code would be used:

	move.w	#27,-(sp)	/escape character
	move.w	#$2,-(sp)	/use Cconout() function
	trap	#1		/use gemdos
	addq.l	#4,sp		/tidy up stack
	
	move.w	#'E',-(sp)	/use Clear screen sequences
	move.w	#$2,-(sp)	/use Cconout() function
	trap	#1		/use gemdos
	addq.l	#4,sp		/tidy up stack

---------	------
    A		Moves cursor up one line. If already at the top of
    		the screen then it has no effect.

    B		Moves cursor down one line. If already at the bottom
    		of the screen then it has no effect.

    C		Moves cursor one character to the right. If already
    		at the right hand side of the screen then it has no effect.

    D		Moves cursor one character to the left. If already
    		at the left hand side of the screen then it has no effect.

    E		Clears the screen and places the cursor at the top-left
    		hand corner of the screen.

    H		Places cursor at the top-left hand corner of the screen
    		without clearing the screen.

    I		Moves cursor up one line. If at the top of the screen
    		then all other lines are scrolled down one line.

    J		Erases all text from current cursor position

    		The cursor is positioned at the start of the new blank line.

    		below it up one and inserts a blank line at the bottom. The
    		cursor is positioned at the start of the current line.
    		
    Y		Positions cursor on screen. The following two values from
    		Cconout() specify the row and column of the cursor. Values
    		are single byte binary numbers and begin at 1.
    
    b		Sets the foreground colour index of the text to be displayed.
    		The following value from Cconout() specifies the colour index
    		to be used. The four least significant bits of the value are
    		used.
    		
    c		Sets the background colour index of the text to be displayed.
    		The following value from Cconout() specifies the colour index
    		to be used. The four least significant bits of the value are

    d		Erases all text from the screen from the beginning of the
    		screen to the current cursor position.
    		
    e		Makes the cursor visible, usually after using ESC 'f'.

    		If the cursor position has not been saved then the cursor
    		is placed at the top-left hand corner of the screen.
    		
    l		Erases the current line that the cursor is on. The lines
    		below it are not scrolled up. The cursor is positioned
