    设 DS=2000H,BX=0100H,SI=0002H,(20100H)=12H,(20101H)=34H,(20102H)= 56H,(20103H)=78H,(21200H)=2AH,(21201H)=4CH,(21202H)=B7H,(21203H)=65H,试说明下列各条指令执行完后AX寄存器中的内容是多少?
    (1)MOV AX,1200H
    (2)MOV AX,BX
    (3)MOV AX,[1200H]
    (4)MOV AX,[BX]
    (5)MOV AX,[BX+1100H]
    (6)MOV AX,[BX+SI]
    (7)MOV AX,[BX+SI+1100H]
