汇编实验6
我的代码是assume cs:codesg,ss:stacksg,ds:datasg
stacksg segment
dw 0,0,0,0,0,0,0,0
stacksg ends
datasg segment
db '1. display '
db '2. briws '
db '3. replace '
db '4. modify '
datasg ends
codesg segment
start: mov ax,stacksg
mov ss,ax
mov sp,16H
mov ax,datasg
mov ds,ax
mov bx,0
mov cx,4
s:push cx
mov si,0
mov cx,4
s0:mov al,3
and al,11011111b
mov 3,al
inc si
loop s0
add bx,16
pop cx
loop s
mov ax,4c00H
int 21h
codesg ends
end start

为什么单步调试后第一行变样了
-d ds:0 3f
