As an example, take the simple case where I have two values A and B, and I
need their sum and their product. Is there a way to do this with one macro?
(my actual problem is a lot more complex,(rotation in four dimensions) but
the principle is the same..)
#macro sum_product(A,B)
#local sum=A+B
#local product=A*B
.......?
#end
// now how do I read sum and product?
Is this at all possible?
