温碧泉眼精华:大虾门来帮我看看代码 最好解释给我听 我菜鸟

<SCRIPT language=VBScript>
dim w,t,p,mm,c,mr,dy,tmp,vs:vs=5:dy=1:p=1:mr="<BR><BR><BR>":c="<font color=white><B>|"&mr:Set w = document.body

sub tp
m=mid(t,p,1):if m="" then c=mr
if m="`" then m="":mm=mid(mm,1,len(mm)-1)
if m="<" then av=instr(mid(t,p),">"):m=mid(t,p,av):p=p+av-1
if m="&" then av=instr(mid(t,p),";"):m=mid(t,p,av):p=p+av-1
tmp=100:if m="." then tmp=400 else if m="," then tmp=200 else if m=" " then tmp=200
if w.scrollHeight-w.scrollTop>w.offsetHeight then w.scrollTop=w.scrollTop+int(dy):dy=dy+dy/vs else dy=1
mm=mm&m:w1.innerHTML=mm&c:p=p+1:if p<=len(t)+1 then SetTimeOut "tp",16+tmp else w.scroll="yes"
end sub

sub window_onload()
w.scroll="yes"
w.bgcolor="#A8A8A8"
w.style.cursor="crosshair"
'-------------------
t=w0.innerHTML
t=ww0.innerHTML + t
tp
end sub
</SCRIPT>
中的 这几个是什么意思
dim w,t,p,mm,c,mr,dy,tmp,vs:vs=5:dy=1:p=1:mr="<BR><BR><BR>":c="<font color=white><B>|"&mr:Set w = document.body
里面的w,t,mm,c,mr,dy,tmp,vs:vs=5:dy=1:p=1:mr什么意思呀
