            I get ;(GO RETURN) ILGL GO OR RETURN - NOT INSIDE A PROG.

        This is because you have your own break loop.  I don't know
        how to fix it, perhaps there IS no way other than to have
        an interpreted PROG around your break loop?

    Sure there is. Just fix your break loop to special-case having read
    (RETURN ...) and P just like Maclisp's break loop.

Oops. We are using this same break loop in a couple Macsyma
subsystems too, MAXTUL and MCL. Thanks for pointing it out.
