>I have several methods using StrToFile( ). All was fine but suddenly the chr(13) has changed from an ascii carriage return to some sort of control code showing itself as a dark rectangle in notepad. I’m not aware of any VFP7 setting I’ve changed that would cause this, nor am I able to find anything in the help files.

You may add a CHR(10) after the CHR(13). To make it generic, you might want to define lcCR at the top of your application and make reference to it. So, if you ever need to change it, you'll only have to change it once.
