assume cs:code,ds:data,ss:stack
data segment
db 'welcome to masm!'
db 2h,24h,1h
data ends
stack segment
dw 0,0,0
stack ends
code segment
start:
mov ax,stack
mov ss,ax
mov sp,6
mov cx,3
mov bx,0
mov ax,0b86eh
mov si,40h
mov di,10h
s1:
push cx
mov es,ax
mov ax,data
mov ds,ax
mov ah,[di]
mov cx,16
inc di
s: mov al,[bx]
mov es:[si],ax
inc bx
add si,2
loop s
pop cx
add ax,0a0h
loop s1
mov ax,4c00h
int 21h
code ends
end start
我调试了一下，代码到mov es,ax
mov ax,data
mov ds,ax
mov ah,[di]
mov cx,16
处的 mov ax,data 运行异常，请求解答！ |
