Thanks, Apfelmus, for the references. Guess I'll start there, then. And thanks, Chris, for the info and code. Read only 'up pointers' could be what is needed. But before going on, I want first to get more confortable with programming with trees. It's all very well to say they're easy to roll, but lists are even simpler, and look at them...
