 So that's how to convert a numeric string from the other end.
Nice!  Easier than I imagined it would be.

TORS is the multiplier, 2ORS is the accumulator. Normally, the multiplier is multiplied after each run with BASE @ - but that makes little sense when IS-DIGIT isn't properly adjusted. Would be a nice exercise, though.
