Hi Josiah 1) You can pull together three operations like this:
<$macrocall $name="rpn" a=<<rpn 20 20 +>> b=<<rpn 3 10 *>> operation="%"/> or like this: \define a() <<rpn 1 2 +>> \define b() <<rpn 3 4 +>> <$macrocall $name="rpn" a=<<a>> b=<<b>> operation="+"/> If you need more you will have to wikify intermediate results. 2) Not really in the sense of true RPN where you could write "100 10 5 1 + * /" but I don’t find that very readabel/understandable so I did not use stacks to store operands and operators in. But as demonstrated in 1 it is possible with some limits. At the moment you can not use macros containing macros or lists as parameters. – Maybe I try to add this later or someone can give me a hint … All the best, Thomas Am Samstag, 8.
