I have been reading a disassembly of part of a program that I use frequently
and found the following XBDOS call in the code...

	move.l	a0,d1
	move.w	#9,d0
	trap	#2

I know trap 2 is used to call extended BDOS functions like AES and VDI,
however the books I have only list the following XBDOS function codes...

	d0	function
	--	--------
	00	System Reset
	73	VDI
	C8	AES

Does anyone (maybe someone at Atari) know what the XBDOS function code 9
does? Is there a complete list of valid (Atari approved) XBDOS functions?
