Multi-letter variables in RPN

[Carsen]

After digging and experimenting, this is how I store a variable

1. Type in the variable name without the tick marks
2. Press ENTER
3. Type in the number you want to store
4. Press ENTER
5. Enter the variable name with the tick marks
6. Press ENTER
7. Execute the STO command
   

It's very inefficient but it works. So for your example if you wanted to store π^2 in the variable ME, press...

[ALPHA] [ALPHA] ME [ENTER] OK (confirm creating the variable with the ok soft key) [Shift] π [x^2] [Shift] [ ' ] [ALPHA] [ALPHA] ME [ENTER] [Shift] [Sto->]

If the variable already exists and you want to store a new number in it, skip step 1 and 2.

I hope somebody knows of a more efficient process. This is the process Joe Horn said to use back in 2014.
