不懂的好多,只好继续问了
假设下列指令从1221开始num dw 12h,0
mov ax,num
mov bx,offset num
mov cl,byte ptr num+1
mov ch,type num
问ax bx cx
ax=0012 bx=1221 cx是什么我就不开不明白了,请版主赐教~~
code segment assume cs:code,ds:code org 100h start: jmp begin org 1221h num dw 12h,0 begin: mov ax,num mov bx,offset num mov cl,byte ptr num+1 mov ch,type num mov ah,4ch int 21h code ends end start写个程序测试一下
