你像下面这样看一下就清楚了:
<%
function abc(m)
response.write("0.<br>")
response.write("n="&n&"<br>")
response.write("m="&n&"<br><br>")
m=m+1 '此时m=n,m加1时,n也加是
response.write("1.<br>")
response.write("n="&n&"<br>")
response.write("m="&n&"<br><br>")
n=n+1 '此时n加1,m也加1
response.write("2.<br>")
response.write("n="&n&"<br>")
response.write("m="&n&"<br><br>")
abc=n+m
response.write("3.<br>")
response.write("n="&n&"<br>")
response.write("m="&m&"<br><br>")
end function
n=5
response.write n&":"&abc(n)&"<br>"
%>
