Don't Ask Me That Question

Did a revision lecture today with the first year programming class. We did all sorts, exceptions, file handling, method parameters, references. I offered to take any question about the course material... Then I got one that I couldn't answer. Ho hum. But then again, I only offered to take the question, not answer it...

Note: The question concerned the use of files in append mode. It is the kind of thing that interactive help systems are made for, and therefore beneath someone with brain power like mine. That's my story, and I'm sticking to it.....
