Afaik you are right. Delphi also allowed the other form, but I thought the syntax would force immediately evaluation of the parameters (and thus only the parameters be stored in case any of a ,b or c are expressions, not all parts of the expressions). But indeed then the other side also has to call it with parameters, and in this example that defeats the purpose. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
