HP Prime - How to STO in RPN mode?
Message #1 Posted by Javier Goizueta on 16 Aug 2013, 11:52 a.m.

I've just begun playing with the emulator and I can't seem to be able to STOre anything into a variable, I only get to create new variables prefixed by the STO arrow symbol!

I guess I'm missing something obvious here...

Enter the number or whatever you want to store, press ENTER, call up single quotes, enter your variable name, press ENTER again, and finally execute STO>

Example:

2: 8

1: 'A'

Stores 8 into A.

Keystrokes: number, [ENTER], [Shift] , [ ( ) ] ( '' ), variable, [ENTER], [Shift], [EEX] (Sto>)

Hi,

At first sight, the 'store' procedure of the HP Prime is close to the same procedure on an HP-28S.

Are you sure that HP Prime isn't emulating RPL mode instead of a regular RPN mode?

I should have known, being a long-time RPL user. (actually I'd tried, but failed to find the single quotes).

Anyway, I found this rather inconvenient in the Prime: the single quotes are shifted, then I need to ENTER before pressing Sto (which is also shifted...)

In the RPL calcs it is much easiear, with ' and STO as primary functions, and with the LeftShift-Softkey shortcut for VAR menus.

I feel this should be improved to make RPL usable, since STOring is such a common operation. Any ideas?

Why RPL at all? RPN would do ...

d:-?

Oops, I meant RPN

"Any idea?"

1/see below about a 'template' idea (value + 3 keystrokes including ENTER). Could [ '¤'|> ] softkey (¤ is a square, and |> the triangle)

2/ Unshifted '' in the unused softmenu

3/ Unshifted STO in the unused softmenu

But only HP could do this. However, it seems very simple things

<<"Stores 8 into A.
Keystrokes: number, [ENTER], [Shift] , [ ( ) ] ( '' ), variable, [ENTER], [Shift], [EEX] (Sto>)">>

Seems like a lot of work just to store a number into a variable. Compare to A=8 in most numerical software running on other handheld devices (e.g., phones, tablets) or number, [ENTER], [alpha], variable, [ENTER], STO in HP48gx.

* In algebraic PRIME :

number 'softkey STO>' ALPHA A ENTER (4 keystrokes)

* On my 50, if the variable exists :

LSHIFT SoftMenu ( 2 keystrokes)

If the Var don't exist

ALPHA A STO (3 keystrokes)

* RPN Prime

Shift '' ALPHA A -> shift STO (7 keystrokes )

I hope this will be improve with the Prime in RPN. A template could be done for this (for example with a STO> in the soft menu (there is nothing inside for now)

'SoftMenu STO>' could give

'' |> (with the cursor between the quotes '' and Alpha locked. 3 keystrokes (with one letter variable, ENTER include)
