Your true = 1 and false = 0 ?
Something like this?
property pFlag
on StartMovie
pFlag = 0
end
on enterFrame me
if pFlag = 0 then
--do what I want here once only
end if
pFlag = 1
end
Are there any other numbers that I can use, besides true/false?

Yes. On hindsight, however , a mouse down may not be such a good idea.
And you helped me by giving me the commands �Send Sprites and �Send All
Sprites�.
I�m grateful.
However, there are several ways to do things, I believe. I�m trying to
figure it how to do it . You have told me that I do need to write my own
code, and then in debugging the rubbish I write, hopefully I learn how to
write better code.
Please allow me to this.

Thank you. I appreciate that � very much.

Sorry, you did say that plus the inefficiency of the code that I had
written.

I�m trying to.

So, it doesn�t matter if no one else understands my code, as long as I
myself can understand it?

If I ask you why, you won�t become frustrated?

In your opinion, how long a preparation time do I require?
May I also ask :
1. In using the getPropertyDescriptionList, I need to keep track of all
the sprites I animate?
2. You used the getPropertyDescriptionList solely for the purpose of
setting the distance to move?
3. When I use the property list, I have to concatenate strings?
Thanks very much. I apologize if I have offended you in any way.
