        Hmm...this is going to be an interesting mini-challenge to whip up a script
that will convert between ash[*] and decimal. I would need to keep track of
whether a zero has already occured or not, as well as some system by which a
preceeding digit can be decremented to either 8 or 7.
        Thanks,

        [*] "ash" is Enamyn for "eight," and it is pronounced /aS/, not /&S/. I
thought it would be less confusing than calling it an octal system, since
"octal" usually implies 0-7, rather than 1-8.
