Pass array as parameter in macro assembly

Is it possible to pass an array as a parameter in macro in assembly? For example,

setXY macro temp[0], temp[1]      ; temp is word-sized
   mov ax, temp[0]
   mov bx, temp[1]

and somewhere in the body you'll call setXY coor[0], coor[1].

Is it permissible?

If you have the following macro:

do_stuff MACRO x, y
  mov ax,[x]
  mov bx,[y]
  add ax,bx
ENDM

And an array of words:

coor dw 1, 3, 5, 7

You could do e.g.:

; Use the do_stuff macro with the first two elements of coor as
; the arguments

do_stuff coor, coor+2

Which would give you ax == 1 + 3 == 4.
