Don't know about HP but fans have discussed this to death, for instance

here

Quote:In the TI-59/58 manual, "Personal Programming", they give the - admittedly contrived - example that can be evaluated left to right with that model's large AOS stack:

(((2x(2x(2x(2x(2x(2+2^(2+.2))-(2+2))))))/2)/2)

That example and all such contraptions is but garbage and proves nothing.

As for the >4 levels RPN stack, I've been using RPN for love and for money for 45 years as of 2020 and written more RPN complex programs than most of you, if not all, and I've never ever ever needed or felt the need for a >= 5-level stack, nor once, quite the contrary.

If in doubt, have a look at my recently published RPN program for the RPN HP-42S. PZER, which finds all complex roots of a, say, 100th-degree complex-coeff. polynomial without ever needing or wanting 5 or more levels. Matter of fact, it won't run in such an "enhanced" stack.

Regards.
