；为什么CX的值是41111h，查看内存，指令明明是用11h赋的值啊
assume cs:code,ss:stack
stack segment stack
a db 'welcome to masm !'
b db 'aaaaaaaaaaaaaaaaa'
stack ends
code segment
start: mov ax,stack
mov ss,ax
mov sp,2*2*(b-a)
mov cx,b-a
mov bx,0
s: mov al,a[bx]
mov b[bx],al
inc bx
loop s
mov ax,4c00h
int 21h
code ends
end start
