Since there is an unlimited stack, the X, Y, Z and T registers are replaced by stack level labels 1, 2, 3, 4, 5, etc. Also there is an unlabeled entry line at the bottom used to enter numbers (instead of overwriting the X register). With this in mind, what you will see with your example is that 45 will be shown on stack level 1 and 78 will be on the entry line. and if I then press / (divide), will it divide 45 by 78? Yes And then X = the answer Yes, except the answer (.576923076923) will be shown on stack level 1. Then I type 50 and now Y = the answer, and X = 50? Almost. The previous answer will be shown on stack level 1 and 50 will be on the entry line. What about on Prime? In RPN mode it should work exactly the same as the HP50 in RPN mode. I am probably making it sound more complicated than it really is. In practice I find the "Entry RPN" logic system used on the RPL calculators (starting with the HP28C) works very similar to the RPN logic system on classic HP calculators, for manual calculations, with only a few small differences. There are other more significant differences of course, particuarly when it comes to writing programs and storing numbers. The calculator also understands many more object types than just real numbers. See the RPL section (http://www.hpmuseum.org/rpl.htm) on the main exhibit page of this site for more information. The following post also explains some of the differences between RPN and RPL models. http://www.hpmuseum.org/cgisys/cgiwrap/...read=87966
