[Newbies] Scrolling Text setCharacters

Hi Steve.

The variable scroll is indeed a undefined in the
method you used. 

To get the results you wanted I tried this.

>From objects pull out a press me button.
Get the halo and press the unmarked light green
button.
That got a "button" tile scirpt.

>From objects>text get a scrollingText.
Using halos get viewer for the scrolling text.
(At this point you can name the scrolling text
whatever you want I made it say "Scroll".)
Pull the tiles  that says "Scroll characters <-" onto
the button tile script.



Now change the button tile script to text using the
check box.
You will see :
Scroll setCharacters: ''

paste the working part of your script before that. And
change the argument from '' to data.

Giving: 

button
  | stream data |
    Transcript show: 'hello'.

"Read file into a string"
    stream _ FileStream fileNamed: 'test.txt'.
    data _ stream contentsOfEntireFile.
    stream close.
    Transcript show: data.
	Scroll setCharacters: data .

Place the mouse over the box that says normal and from
the menu pick the action you want to trigger the
script (say mouse up for example )
press and release the button. And you get your text in
the transcript and the scrolling text.

The ritual we did with the tiles insured that Scroll
refered to the desired object namely your text morph.

There are probably other ways to insert the reference
but this was the one I tried first because I figured
it would work. 


Yours in service, --Jerome Peace
