Looking at all of your questions, I think what you're trying to ask is
if you can use the LHS of a rule like a procedural nested if
statement. You probably want to call a function in one pattern and
then use the return value of that call in another pattern. The short
answer is that no, you can't do that, it just doesn't work that
way. The slightly longer answer is that if it worked that way, much of
the advantage offered by the high-performance Rete algorithm would be
sacrificed.
In any case, if you find yourself needing to do this, then what it
means is that you should be writing deffunctions instead of defrules
-- i.e., if you need to write procedural code, go ahead, write a
procedure!
