第一个：

assume cs:code,ds:data
    data segment
    	db 0h
    data ends
    code segment
    start:mov ax,data
    		mov ds,ax
    		mov bx,0
    		jmp word ptr [bx+1]
    		
    		mov ax,4c00h
    		int 21h
    code ends
    end start

第二个：

assume cs:code,ds:data
    data segment
    	dd 12345678h
    data ends
    
    code segment
    start:mov ax,data
    		mov ds,ax
    		mov bx,0
    		mov [bx],bx;此处必须满足直接赋予4个0！
    		mov [bx+2],cs
    		
    		jmp dword ptr ds:[0]
    		
    		mov ax,4c00h
    		int 21h
    code ends
    end start

第三个：

代码：

assume cs:code,ds:data
    data segment
    	dd 12345678h
    data ends
    
    code segment
    start:  mov ax,2000h
    		mov es,ax
    		jmp dword ptr es:[1000h]
    		
    		mov ax,4c00h
    		int 21h
    code ends
    end start
