Pauli

I didn't think of that! I'll add ∑LISTR command to do summation from end to start in newRPL, and let the user decide which direction the summation goes. While using REVLIST is fine, it's much slower than just adding in reverse order.
Can't do the reverse by default all the time because in RPL ∑LIST could very well be concatenating strings...
