把寄存器全部设置成0的状态，然后执行下面的代码：

mov eax,0a1234h ;将十六进制数0a1234h送入eax
mov bx,ax ;将ax内容送入bx
mov ah,bl ;将bl内容送入ah
mov al,bh ;将bh内容送入al
思考此时EAX的内容是多少？
答：mov eax,0a1234h ;将十六进制数0a1234h送入eax ,此时ah的值为12h,al的值为34h
mov bx,ax ;将ax内容送入bx
此时bh的值为12h,bl的值为34h
mov ah,bl ;此时ah的值为34h
mov al,bh ;此时al的值为12h

则此时EAX的值为a3412h
