RPN Calc Help
Last updated: 2002-12-20
RPN Calc is a bit of a clone of the HP11 RPN calculator, with only a few functions implemented.
The calculator is stack based, as follows: X (Top), Y, Z, T (Bottom)
There are 10 memory registers: R0 - R9
Keys:
+,-,/,X - operates on X and Y, result placed in X
Enter - Pushes the contents of the display onto the top of stack
BS (Backspace) - deletes the last number entered
1/X - returns the inverse of X
x<>y - swaps the X and Y values
ROT - Rotates the stack, X to T, Y to X, Z to Y, and T to Z
RCL - returns the contents of the memory register pointed at by the value
of the X register (must be an integer)
STO - the value in the Y register is stored in the memory register pointed
at by the X register
