Text View In Applescript Studio Pro

I want to write some output to a text view in Applescript Studio, How do I do this?

set contents of text view 1 of scroll view "theView" of window "theWindow"

The text view is actually inside of a scroll view all the time, so just name the scroll view and use this code.

Thanks you for the response, however I want to continually update the textview with new text, that is I want to append text to text that is already in the text view… is there any way of doing this?

set currentText to contents of text view 1 of scroll view "theView" of window "theWindow"
set thisText to "some text to append"
set contents of text view 1 of scroll view "theView" of window "theWindow" to currentText & thisText
