Title A 4 Level RPN emulator based on the HP-35 calculator.
Description With this program you can understand and practice the RPN's logic with a comestible run speed. The 4 Level RPN is an early RPN version. A four level stack is sufficient even for very complex expressions. It was used first on the HP-35 calculator in 1972. The HP-35 was the first pocket calculator with transcendental functions and the first with RPN. The program is based on this machine. My goal was: To write a correct stack emulator of a more simple but faster scientific calculator. The emulator's functions are shown on the screen shots. What you see is what you get. IO screen programming: The controlled write command is the >Output< but it's very slow. The >Disp< is faster, but it isn't controllable. You can control the >Disp< with an empty >Output row,col,""< command. Update: See update.txt
