FileOpen with a .set file?

 
How would my FileOpen statement have to look if I wanted to read a tester .set file? FILE_READ|FILE_CSV, FILE_READ, or FILE_BIN|FILE_READ ?
 
A set file is a collection of lines in the form name=value, not binary, not csv
 
So just FILE_READ then? What delimiter should I use? is it possible to use '\n' ?
