;Hi Ralph !
;Simple STACK trick !
;Sucks all known debugger ! (DEBUG,TD,SST,MMD)

		jmp	start
;--------------
body		xor	ax,ax
		.
		.
		.
		program body
		.
		.
		.
aaab:		jmp	short cont
;--------------
start:	!!	int	1  
	!!	mov	bp,sp
	!!	mov	al,byte ptr [bp-6]

						lea	bx,body
						mov	cx,start-body
				bont:		xor	byte ptr [bx],al
						inc	bx
						loop	bont

	!!	sub	word ptr [bp-6],2+(start-aaab)
	!!	sub	sp,6
	!!	iret
