我有些程序在8.0上运行很好，但在8.5上就不行。有人能告诉我关于它们lingo用法上的一些不一致之处吗？谢谢。（非3d lingo和Multiuser lingo)

It's seemed very strange. I don't know what's wrong with it . You can
download that file from: www.irisdream.com/sound4.dir

All things will be fine before you have a view of that code .you can play it
in Director. But after you view the behaviour named 'B_sound button' I gived
below, you can never play the movie anymore.Just a pup-up window tell me
that:" Script error: Variable used before assigned a value."

What's wrong with that , and how to fix it?

Finally I found it worked well with Director 8.0 . But I use Director 8.5.

What's the difference?

-- sprite ref, ie (sprite 1)
property pSprite

-- member refs, ie (member 1 of castLib 1)
property pUpMember
property pDownMember

on beginSprite me
  pSprite = sprite(me.spriteNum)
end

on getPropertyDescriptionList me
  myList = [:]
  myList[#pUpMember]   = [#comment: "Up state:", #format: #graphic,
#default: 1]
  myList[#pDownMember] = [#comment: "Down state:", #format: #graphic,
#default: 1]
  return myList
end

on mouseUp me
  pSprite.member = pUpMember
end

on mouseDown me
  pSprite.member = pDownMember
end

on mouseUpOutside me
  pSprite.member = pUpMember
end

解决了，不知道怎么回事，分隔符打开后变成了怪字符。
