I don't see why. It's a keystroke programmable. the programs are pretty much the same as the keystrokes you'd hit to solve the problem manually. Add some LBLs and GOTOs for looping and add a R/S for any place you'd like to enter a variable at run time. That's about it for a basic (not BASIC) program. Of course there are many other features but those are used if you want to make the program fancy. You already know how to calculate manually using RPN so writing a program in it should be a piece of cake (easy as pie)
