直接看源码吧：（25行）
assume cs:codesg
data segment
db 'welcome to masm!'
data ends
codesg segment
start: mov ax,data
mov es,ax
mov bx,0
mov ax,47104
mov ds,ax
mov cx,16
s1: mov al,es:[si]
mov ah,2h
mov ds:[bx+1984+si],ax
mov ah,42h
mov ds:[bx+2144+si],ax
mov ah,71h
mov ds:[bx+2304+si],ax
inc bx
inc si
loop s1
mov ax,4c00h
int 21h
codesg ends
end start
下面是 （30多行的--理解错了题目意思，还以为在显示区只有那三行英文呢！）
