It's Good ! – Active RPN Calculator Review

For a basic RPN calculator this fills the bill. Nice features are the visible stack at all times, and having both a Last-X and Last-Y functions. I'd give five stars if it had a way to halt program execution (as in R/S on HP calculators) to allow further inputs or to view intermediate results during the program. Very nice are the illustrations & diagrams that educate us as to how the functions operate.
