What's fileName set to initially?

Actually, my initial thought when I saw this code was, "that actually works?!" I tried out a simpler version of it, and it seems to work OK (I removed the code which accesses the filesystem - it just appends a character to a test string. Still, it might be because of the evaluation order of things. You could try moving the fileName assignment above the while (then duplicating it inside of the while after your // Do all my stuff code has run) to see if that's the case.
