I am using eCalc and just now tried both key sequences above.

In eCalc, both of the above sequences result in an answer of 1

However, the second method (without the extra [Enter] is probably=20
more correct and is what I would have used with my old HP-45 if it=20
still worked.  That's because the old HP calculators have only 4=20
levels of stack.

However, in a calculator that has more than 4 levels of stack (like=20
eCalc), both sequences are valid RPN.
