... every memory location is a stack.

I'm thinking of a notation like:

    A => CADR (yes, I'm a LISP fan)

    A' => A[0]

    A'' => A[-1]

etc.

Not quite APL\360, but I guess pretty close :-)

dc(1) has 256 registers identified by a byte.
Each can be treated as a stack, stored to and loaded from with S and L.

Cheers, Ralph.

Jeeze, I'd forgotten about DC; thanks!
