Horizontal Scroll Text

Question

I found a cool new font and would like to scroll text like a
news ticker. I have created my dynamic text box, set it up the way
i want the text to look, and set it to scroll. I know how to write
the code for a vertical scroll, how would i set it up to scroll
horizontally?
the text in the text box wants to set itself up as vertical
lines instead of horizontally as well. How can i change that?
Thanks for the help.

Here's some code for a horizontal text scroller I just threw
together.
horizontal_txt.autoSize = "left";
horizontal_txt.text = "Lorem Ipsum is simply dummy text of
the printing and
typesetting industry. Lorem Ipsum has been the industry's
standard dummy
text ever since the 1500s, when an unknown printer took a
galley of type and
scrambled it to make a type specimen book. It has survived
not only five
centuries, but also the leap into electronic typesetting,
remaining
essentially unchanged.";
var intervalId:Number;
function scrollMe():Void {
horizontal_txt._x -=20;
if (horizontal_txt._x <= -horizontal_txt.textWidth) {
horizontal_txt._x = 550;
intervalId = setInterval(this, "scrollMe", 100);
Basically, I'm just moving the text box -20 pixels in the _x
position each
time the function is called (you can mask it if you'd like).
Once it determines that the inverse of the width of the text
in the textbox
is less than or equal to it's _x position, it resets the
textbox back to the
right edge of the play area.
To test, just make a dynamic, single line textbox named
horizontal_txt and
place it at 550 on the stage.
You could get more sophisticated and have an array of news
that it cycles
through, and have it pause if the mouse of over, etc. I'm
sure you've seen
those things before.
Anyway...let me know if you have any problems implementing.
