I find myself often doing either: function Bla(parameters): integer; - > returns => 0 for success/value returned, < 0 for error and upper layers recognize the error codes (this is pretty much like c common usage you can find in c programs) or function Bla(some_params; out ErrorMessage: string):boolean; or function Bla(some_params; out ErrorCode: integer): some_type_other_than_integer; so it's not like you /can't/ return more than one value... but you need to prepare yourself for it ;) L. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
