代码:
assume cs:sad sad segment start: mov ax, 0ffffh mov ds, ax mov dx, ; add ds:0bh~ds:1h mov cx, 0bh s: mov ah, mov bx, cx mov al, ds:[bx] add dx, ax loop s ; add ds:0h mov bh, mov bl, ds:[] add dx, bx mov ax, 4c00h int 21h sad ends end
自己写的==
下面是看了书上的之后,写的:
assume cs:sad sad segment start: mov ax, 0ffffh mov ds, ax mov dx, mov bx, ; c = b + mov cx, 0ch s: mov ah, mov al, [bx] inc bx add dx, ax loop s mov ax, 4c00h int 21h sad ends end
主要是加上了inc bx的用法==
