Is There A 39gII Applet or Program yet which does RPN? - Jake Schwartz - 10-04-2012 Hi, I was just wondering from the 39gII user community whether anyone has yet attempted to fashion a program or applet which would simulate run-mode RPN on that machine. It seems like it would be a fun project.
Thanks, Re: Is There A 39gII Applet or Program yet which does RPN? - hpnut - 10-04-2012 I support Jake's suggestion. To me, HP calculators must have RPN. cheers,

Re: Is There A 39gII Applet or Program yet which does RPN? - C.Ret - 10-05-2012 Be aware that an advanced calculator manipuling vectors, matrix, list, local variable as well as private subroutine, symbolic expression is closer to an RPL calculator than an RPN one ! :-)

Re: Is There A 39gII Applet or Program yet which does RPN? - Eddie W. Shore - 10-05-2012 I will have to look at my notes, but I think I have done an RPN program for the 39G once.
Re: Is There A 39gII Applet or Program yet which does RPN? - Gilles Carpentier - 10-05-2012 Long time ago, I wrote in Turbo Pascal an interpreted RPN language wich was a mixt of RPL and Forth With the powerfull embeded language of the 39gII it is possible to write this. But i see some big limitations about :
- Interactive usage and displaying stack
If I have some time I will try what it can be do ....
Re: Is There A 39gII Applet or Program yet which does RPN? - M. Joury - 10-22-2012 I wrote a program for the 39gs that supports basic RPN. About the level of an HP35 or perhaps an HP45. Don't know that it would work on a 39gII though. If I ever pick up a 39gII I will convert it to that platform.

Re: Is There A 39gII Applet or Program yet which does RPN? - Namir - 10-31-2012 Hello Maruan, There is no 39gII app for RPN. The closest I can think of (and I have been using that machine a lot recently) is a series of function(s) that initialize the stack (in a column matrix that has 4 rows representing the stack) and then using other functions to execute math operations and evaluate functions. Each function would return the matrix that simulates the stack. This is a simple approach, but might actually works by using the Pascal-like programming language of the machine.
