No precedence: keep grouping left to right. This is/was the original state, but as John pointed out in the MEX paper, people will perversely not follow it, (as he then went on to do in the quadratic example in the same paper). > 2. Invent new or press into duty existing cmavo to RPN is in MEX - introduced by cmavo "fu'a", I think. MEX has prefix (polish), infix and postfix (reverse polish) all provided and even mixable, with suitable cmavo. Beings with logical minds and large short-term buffers will of course prefer either of the outer two, mere humans will probably continue on a roll of hundreds of years and stick with infix. kolin c.j.fine@bradford.ac.uk
