Android App for HP48 1

[SE2607]

I have two apps on my Android phone which simulates an HP48:
Droid48
48sx
I have a real HP35s.
Problem:
On my HP35s, when I want to store a number, I press STO then a key. The key I most often use is the upper left hand one marked "A". When I want to recall that number, I press RCL and then "A".
When I try to do the same thing, right after I press STO (and before I press "A"), I get an error: "too few arguments". This occurs on both apps.
What am I doing wrong?
Thank you

STO

object to store on line 2
register to store in on line 1

access the stored value via the "VAR" menu

Thanks for the reply, Celt83.
What is the character between "enter" and "alpha"?
Thank you

Never mind. I got it. That's a lot more keystrokes than on my physical 35s!

Yep but comes with more freedom on how you store items on the 48.

Also the 48 uses RPL while the 35s uses standard RPN (4 level stack)

you can get the user manual plus some other random manuals for the 48 from here: https://literature.hpcalc.org/

Thanks.

Where can I find other differences between RPL and RPN?

Funny, I don't think I have used the STO function on my HP15 (real and emulated) in 20 years.
