comparing numbers on the WP 34S « Next Oldest | Next Newest »

I'm trying to compare the value in X with a value stored in a register. I see how to do it indirectly (using the right-arrow). I see how to do it with a register numbered 20 or higher. I see how to do it with a local register. But how do I do it with a global register numbered below 20? When I press 0 or 1 it assumes I want to compare X with 0 or 1 (and yes, I realize these constant comparisons are available). Can I compare the contents of X with, say the contents of Register 05? Or do I have to do a RCL 05 and then compare X with Y? ▼ Dieter Senior Member Posts: 653 Threads: 26 Joined: Aug 2010 10-18-2013, 03:17 PM Simply press [ENTER] before the register number: ``` [f] [x=?] x=_? [ENTER] x=? _ [0][5] x=? 05 ``` Dieter ▼ Kiyoshi Akima Senior Member Posts: 325 Threads: 18 Joined: Jul 2006 10-18-2013, 03:36 PM Thank you!

STO+ Z is another one that isn't immediately obvious. Locating the '0' and '1' for comparisons without dumping into the alpha keyboard took a couple of go arounds. - Pauli Walter B Posting Freak Posts: 4,587 Threads: 105 Joined: Jul 2005 10-18-2013, 09:38 PM You find two pages explaining memory addressing in detail between p. 20 and p. 35 in the manual v3.0, 3.1, as well as 3.2 IIRC (I'm off home right now - a bit closer to Pauli but way north). d:-) Edited: 18 Oct 2013, 9:40 p.m. ▼ Kiyoshi Akima Senior Member Posts: 325 Threads: 18 Joined: Jul 2006 10-18-2013, 10:58 PM Okay, now I see it. On page 26 it says that ENTER leaves the alpha-t mode. Thanx. ▼ Marcus von Cube, Germany Posting Freak Posts: 3,283 Threads: 104 Joined: Jul 2005 10-19-2013, 08:52 AM There is another, no so obvious, shorthand to enter X as a register name: Precede it by a dot. Since X is on the same key this results in a double dot. ENTER dot does the same here but the double dot is quicker to type. ▼ Walter B Posting Freak Posts: 4,587 Threads: 105 Joined: Jul 2005 10-19-2013, 09:28 AM Yeah, some special wishes caused quite some consequences in the layout ... d:-)
