Illustrator Scripting :: How To Read Text File Into TextFrame

I'm trying to read a text file into a textFrame.  It reads in but is not including linefeeds so it's just one big long line of text.  I'm using the following code to read the file.  I attempted to insert a character after each readln() but that didn't work.  I also tried creating a variable that the readln() was stuffed into before setting the textFrame.contents to the variable, but that didn't work either. I'm stumped.
 
while (! notesDoc.eof) {
noteTextRef.contents += notesDoc.readln();}
