Since the RPN mode pops the values off the stack, how does one pass multiple variables to a function? For example R->B has the following syntax:

R->B(Real [,bits [,base]])

In textbook mode, R->B(8,64,1) gives the result #1000,64b which is correct.

How would I do that in RPN mode? It seems I can only pass the first value of the stack. I could write a program with INPUT() calls for each value passed to the function, but I'm thinking there is a way to use these functions natively in RPN mode.

The calculator does not seems as intuitive to me as far as base conversion go in comparison to the 48G. I need to work on this and it seems like these functions are the way to go? If so, in addition to the present functionality, it would be nice to overload the R->B function to skip the bits part. R->B(Real, base) would be a nice one to have in addition to the one presently available.

Thanks.
