<CAN> is a single character, as I wrote above.  For example, put into
your syslinux.cfg the line

DISPLAY splash

then the file named 'splash' could contain this (in octal dump):

$ od -c splash 
0000000 030   s   y   s   .   l   i   n   u   x   .   r   u   l   e   z
0000020   .   l   s   s   1   6  \n
0000027

Here 030 octal = 24 decimal is <CAN> and \n is <newline>, which is 10
decimal.  The other characters stand for themselves.

And of course you've got to have sys.linux.rulez.lss16 available as
well.

No, DISPLAY does it if it finds the command (that is, <CAN>) to display
graphics.
