Yes, but remember I am doing algebra not arithmetic. That is, I am
constructing

/\
A &

B C
Where A, B, and C evaluate to T or F.

Yes, I agree, that sounds attractive. After I gave it a bit of
consideration, I realized it wasn't quite as obvious as it first seemed. I
have taken a course in C++ but haven't really used it since. If you haven't
stepped through algorithm I presented you may wish to. I believe it will
construct the tree. Perhaps I will attempt this in C and we can compare
notes. I'm supposed to be working on an MCSE right now instead of learning
to program. Yuck!

Yea I've been playing with perl. It really is fun. I'm not sure what data
structures perl will offer for such a problem. You may be able to code this
whole thing in one line of perl which no one in the world will understand ;-)
