I use an RPM calculator and have for decades. My big gripe is that my
HP-16 doesn't tell me how deep the stack currently is and doesn't err
out when I try to pop the stack beyond what's been pushed. Nor do they
tell me when I've tried to push something beyond the T register.
Of course, infix calculators usually don't tell you that the cell that
you're recalling doesn't contain anything.
Either deficiency could have been solved with just a simple flag that
distinguishes between a register/cell that's empty or one that contains
data.
Has this been remedied in any of the newer RPN calculators?
