I think you are refering to DRI's GSX (or Graphic System Extension) That runs
on *86 and 68K and z-80's. If not, skip this. Else Here is the binding
information.

Gsx is a cut back implementation of GKS. It follows GKS pretty closely and
dropped those items that couldn't be done with the horsepower of a micro.

The binding information is:

	mov	ax, seg d_ptr		; get segment of the data ptr
	mov	ds, ax
	mov	dx, offset d_ptr	; ds:dx points to data area
	int	224
	test	ax, ax			; check ax for return code
	jnz	error
...


	Dseg

[Add[C[C[C[C[C[C.
d_ptr	dd	adr(ctlseg)		; dword address of control segment
	dd	adr(ininseg)		; dword address of input integer segment
	dd	adr(inoutseg)		; dword address of output int segment
	dd	adr(ptinseg)		; dword address of input pt array
	dd	adr(ptoutseg)		; dword address of output pt array

For more information, Check out "GSX programmer's Guide"
