That's a nice program and, as far as I can tell, it seems to work correctly.

But you should remove this line from the example:

Unlike the previous pricing program, this one does store a calculated result in the respective register. So you do not have to re-enter it if you want to continue with this value.

In this example a new input isn't required even if the result had not been stored. You just have calculated FV, and now you change the interest rate to calculate a new FV. So the old one is overwritten anyway. You do not need the old FV to calculate a new one. ;-)

The code looks very good. However, if possible, I would avoid clearing all registers. This way the user loses all data he may have stored. So it's always a good idea to clear only the required registers. At least on a calculator with constant memory.

Code:

STO 1
STO 2
STO 4
STO 5
FIX 2
RTN
