Statement evaluation stack.

	  A - Q - V
	  !
	  B - C - D - E
	  |  [!]
	  !   R - N - Z
	  !
	  F - G - H

So; next is

F, G, H, B, C, R, N, Z, D, E, A, Q, V

So;
			next	frame->data	[after]
Push A, next = A,	A	A		A
Push B, next = B,	B	B		B
Push F, next = F,	F	F		F
        next = G	0	F		G
        next = H,	0	G		H
Pop,    next = C,	0	H -> 0		C
Push R, next = R,
        next = N,
        next = Z,
pop,    next = D,
	next = E,
pop,	next = Q,
	next = V
