Thanks for the tips, John, above all regarding the cleaner & more logical 2 n START... NEXT, that, besides memory saving, for 1 million loops/start seems — logically — to reduce the execution time by a factor of 1.001 in comparison to 1 n 1 - START... NEXT.

IF "condition" THEN... ELSE...
is, yes, clearer than "condition" IF THEN... ELSE: an habit from RPN logic.

DUP DUP is just safer — to include potential users of
the old HP48 that can't use the new, faster command DUPDUP.
