The top level function could be a function of one (string) argument, as for exemple : (calculator ³(5*9+3)/200²) => 0.24 Thanks Denis ------------------------------------------------------- Denis Pousseur 70 rue de Wansijn 1180 Bruxelles, Belgique Tel : 32 (0)2 219 31 09 Mail : denis.pousseur@gmail.com -------------------------------------------------------
