I am using an NSTextView and I want to update the textview each time I go through the repeat loop… I am using the code below at the moment but it is clearing the contents of the textview each time I go into the repeat loop where as I want to append to text within the TextView window.

repeat with appname in thelist
set outputstr to "Launching " & appname & " "
set the contents of text view 1 of scroll view 1 of window 1 to outputstr
end repeat

#2 
set outputstr to ""
repeat with appname in thelist
set outputstr to outputstr & "Launching " & appname & " "
set the contents of text view 1 of scroll view 1 of window 1 to outputstr  
end repeat
