It doesn't seem possible to me, either, but it wasn't my story. :-) However, I could see someone writing 20,000 lines of code in a high-level language like C++ or Java without comments. If you have good variable and class names, you could probably get by and have a small chance of being able to maintain it. (so-called "self-documenting" code. It's not a good idea, by any means, but it would be possible. Alex -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
