你的程序好像也没问题呀！除了代码有点长……
assume cs:code,ds:data
data segment
db '1. display '
db '2. brows '
db '3. replace '
db '4. modify '
data ends
code segment
start:
mov ax,data
mov ds,ax
mov bx,0
mov cx,4
s0:
push cx
mov si,0
mov cx,4
s: mov al,[bx+3+si]
and al,0dfh
mov [bx+3+si],al
inc si
loop s
add bx,16
pop cx
loop s0
mov ax,4c00h
int 21h
code ends
end start
