在Debug中,用-d 0:0 1f 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
下面程序执行前,ax = 0, bx = 0. 填空。
mov ax, 1
mov ds, ax
mov ax, [0000] //ax =
mov bx, [0001] //bx =
mov ax, bx //ax =
mov ax, [0000] //ax =
mov bx, [0002] //bx =
add ax, bx //ax =
add ax, [0004] //ax =
mov ax, 0 //ax =
mov al, [0002] //ax =
nov bx, 0 //bx =
mov bl, [000c] //bx =
add al, bl //ax =
能写出答案并能解释一下。
