More precisely, L/ukasiewicz invented Polish Notation. Reverse Polish Notation is just Polish Notation written backwards. I first encountered Polish notation while studying symbolic logic; certain proofs are easier when well-formed formulas are written in Polish Notation. The notation is reversed when used for calculation because then it's easy to process the formula by pushing/pulling tokens and values on/off a stack. =========================================================================== Dennis Paul Himes <> Gladilatian page: Disclaimer: "True, I talk of dreams; which are the children of an idle brain, begot of nothing but vain fantasy; which is as thin of substance as the air." - Romeo & Juliet, Act I Scene iv Verse 96-99
