assume cs:codesg
codesg segment
mov ax,4c00H
int 21H
start:mov ax,0
s:nop
nop
mov di,offset s
mov di,offset s2
mov ax,cs:[di]
mov cs:[di], ax
s0:jmp short s
s1:mov ax,0
int 21H
mov ax,0
s2:jmp short s1
nop
codesg ends
end start
--------------------------------------
为什么最后jmp到了ax -<4c00H这一行,而不是ax-<0这一行呢??
