[WP 31s] difficulty with STO/ RCL X Y Z T - Stephan2 - 10-19-2014 05:26 PM
Hi Everyone, my WP 31s works fantastic, just one thing I can't figure out: How does STO/ RCL work with registers X to T? The preliminary owners manual version 1.2q says on page 30: "Note that you will not need [f] in αT except for addressing the four lowest stack registers." [i.e. X, Y, Z, T] I understand that for X to T, I do need [f]. So what I do is: RCL [f] [y] to recall the Y register. Instead I get the content of R2. Effectivly, the calculator seems to ignore the [f] key in this situation. In this situation, the f indicator does not light up in the display, normally it does. What am I doing wrong? My firmware version is 3671. Thanks everybody for advise and of course for this very nice calculator. Kind regards, Stephan RE: [WP 31s] difficulty with STO/ RCL X Y Z T - BobVA - 10-19-2014 06:09 PM
I believe to access X, Y, Z and T you actually need to prefix the register with the ENTER key. For example: 17 STO ENTER T will put 17 in the T register RCL ENTER T will recall the value in the T register. (Please see the table about "Addressing Real Numbers" on Page 27 of the WP34 manual for the definitive discussion!)

For example: You can also use the period/decimal key: 17 [STO] [.] [T] ---> [EDIT - This is wrong! - use the ENTER key] [RCL] [.] [T] One slight advantage to using [ENTER] vs [.] is that the calculator displays an 's' indicating you are accessing a shifted memory location. (I do not recall if the 's' actually indicates 'shifted', but that seems likely.) With [.] there is no indication--but it works. This also seems to work with the register arithmetic functions. [EDIT - This is incorrect. Use the [ENTER] key! See below.] -Jonathan RE: [WP 31s] difficulty with STO/ RCL X Y Z T - Stephan2 - 10-19-2014 07:51 PM
Thank you both for your advice. Using [.] doesn't seem to work on my calc (strange?), but [ENTER] works perfectly, including arithmetic functions. Best, Stephan RE: [WP 31s] difficulty with STO/ RCL X Y Z T - Jonathan Cameron - 10-19-2014 08:03 PM

I can update the firmware, but it will take until next weekend. Here's what I do: [f] CLEAR RESET [y] -> Erased 123 [STO] [+] [.] [x] -> 123 (wrong) 123 [STO] [+] [ENTER] [x] -> 246 (right) I can live with just the [ENTER] way, obviously. But indeed it's odd.

When I waas doing [STO] [.] [T] I was actually storing into register 4---I just thought it was register T! I should have checked with [ENTER] to verify. So definitely use [ENTER], as it says in the the 31s manual. -Jonathan RE: [WP 31s] difficulty with STO/ RCL X Y Z T - Stephan2 - 10-20-2014 09:58 AM
Ok, another mystery solved then. ;-) Thank you all again for your help. |
