add text to an exsisting text file w/o overwriting

[bagonterman]

I am creating a text file that will tally information from a UI. My hope is that I can add information as buttons are clicked. But when I write to the text file it over writes what is already there. 

myFile.writeln("\r\n",mySFolder,"   ",myCountText.text, );

I am wondering how to append to the text file.

Here is an example...

var Log =File(Folder.desktop +"/LogFile.txt");
Log.open('w'); //open a new document
Log.writeln("This is a log file");
Log.close();
Log.open('e'); //open for append
Log.seek(0,2); //seek to end of file
Log.writeln("Write text to re-opened file");
Log.close();

Paul e is edit… a is append… Your version however works pre-cs4 versions…

Thanks Mark, like me it's OLD

When I used 'a' it did not work. I am using CS5 Bridge.

This works with Windows 7 and Bridge CS5.

var Log =File(Folder.desktop +"/LogFile.txt");
Log.open('w'); //open a new document
Log.writeln("This is a log file");
Log.close();
Log.open('a'); //open for append
Log.writeln("Write text to re-opened file");
Log.close();

I am using OS 10.6.8.  'e' works for me. I am wondering if I will have any trouble when I switch to Windows 7?
