Hm. I've read that Tech Note too, I think.

Um. The same version that just opened thirteen files with no problems. I
guess I'm going to have to do a bit more exploration.

My question still stands, though- what are those doohickeys (FCBs?) for?
Data forks, Resource forks, or both? if both, do I use up two slots if I
open both a file's data and resource forks? I had originally assumed that
they were for the data fork only...
