汇编循环代码-----个人觉得汇编中最好玩的代码

assume cs:codesg,ss:tacksg,ds:datasg

stacksg segment
dw 0,0,0,0,0,0,0,0
stacksg ends

datasg segment

db ‘1. display ‘
db ‘2. brows ‘
db ‘3. replace ‘
db ‘4. modify ‘
datasg ends

codesg segment
start:
mov ax,datasg
mov ds,ax
mov ax,stacksg
mov ss,ax
mov sp,16
mov bx,0
mov cx,4

s0:
push cx;
mov si,3
mov cx,4
s:
mov al,[bx+si]
and al,1101111b

inc si
loop s
add bx,16
pop cx
