RPN and result storage in a variable

[hatchcanyon]

Hello!

I'm quite new on an HP Prime but work with HP calculators starting in 1985 or 1986. First one was an HP 15C, lateron an HP 28S. The 15 is still up and working, the 28 has now trouble with keys. Therefore I changed to the Prime.

Naturally I want to work with RPN only but have problems. LLet me describe what happens:

- I perform a RPN calculation.
- The calculator delivers a result.
- I triy to store the result in a variable.
- whatever I try this does not work for me. Either I get a syntax error message or the variable only contains the value "0".

In CAS mode storing results in a variable works fine.

What do I do wrong?

Thanks for any help!
