(1) 在DEBUG中,用 "D 0:0 lf" 查看内存,结果如下:
0000:0000 70 80 F0 30 EF 60 30 E2-00 80 80 12 66 20 22 60
0000:0010 62 26 E6 D6 CC 2E 3C 3B-AB BA 00 00 26 06 66 88
下面的程序执行前,AX=0,BX=0,写出每条汇编指令执行完后相关寄存器中的值
mov ax,1
mov ds,ax
mov ax,[0000] ax= 2662H
mov bx,[0001] bx= E626H
mov ax,bx ax= E626H
mov ax,[0000] ax= 2662H
mov bx,[0002] bx= D6E6H
add ax,bx ax= FD48H
add ax,[0004] ax= 2C14H
mov ax,0 ax= 0
mov al,[0002] ax= 00e6H
mov bx,0 bx= 0
mov bl,[000c] bx= 0026H
add al,bl ax= 000CH
用DEBUG进行验证：
