Action Script - Controlled Loop

Question

I know the most basic command in ActionScripts to keep my
Flash video from looping (stop();). Can I apply that command
if I want
to end on a scene used previously in the movie (as in the
example in
the
notes)? How does that work such that my movie doesn't stop
after the
initial use of that scene and go no further?
Ideally, I would like to use the same scene as an opening and
closing
sequence to my movie. However, after the second use, I would
like to
have text saying "The End." Is there an if/then statement
that defines
if this has played before or something?

Answer 1

for smooth scrolling like your website you would control the
_y property of a movieclip and yes, that can be done with
actionscript.
