Access RPN stack result in PPL program?

[jayhawk]

You can read from the stack/history from PPL, no matter what mode you are in.
I use this tecknique to make my programs work in the same way in all three entry modes:

Code:


export showstack()
  local x,y,z,t;

  x:=Ans(1);
  y:=Ans(2);
  z:=Ans(3);
  t:=Ans(4);

  return {x,y,z,t};
end;

This program takes it's arguments from the stack/history no matter if the prime is in RPN, Textbook or Algebraic mode.

However it would be nice if you also could:

Code:


  Ans(2):=7*17;

It would also be nice if a program only returns a value if RETURN is used.
Then we would have an almost true RPN capable calculator!
