This is indeed what I meant, i.e. on input
X : B AND C;
P(A|X) : a;
P(B|C) : b;
Then ask for the value of P(AB|C) and get a*b in response.

Thanks - it will save me some vain effort!
Perhaps you know some other software which supports this sort of algebra?
(The closest I can think of is Bayesian network software, but it is
non-symbolic and expects specification of factorized probability
distributions as input.)
