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~~

程序代码: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
