Yes, that is needed in old AXIOM systems and any other AXIOM-descendant that uses implicit conversion from $ to Rep and vice-versa. OpenAxiom's choice (that Bill Page described early) prevents that surprising behaviour, for everybody's sanity. Therefore, the $Rep is never needed in OpenAxiom code that uses per and rep (the whole point of the exercise!) See also http://sourceforge.net/mailarchive/message.php?msg_id=18430416 if you are interested in having that in your favorite AXIOM flavour. -- Gaby -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
