WP 34S - indirect addressing issue Message #1 Posted by Gerson W. Barbosa on 22 Jan 2012, 4:57 p.m. I've noticed indirect addressing doesn't work when the fractional part of the index is equal or greater than 0.5. Of course, by definition indices are integer numbers. However, as a convenience, HP calculators accept non-integer number as indices for indirect addressing and just ignore the fractional part. Is this a WP 34S bug or a feature? Thanks! Gerson.

Re: WP 34S - indirect addressing issue Message #2 Posted by Paul Dale on 22 Jan 2012, 5:06 p.m., in response to message #1 by Gerson W. Barbosa It seems to be working: 1 STO 01 2 STO 02 1.75 RCL-> X Returns 1 as it should. In other words, I'm not understanding the problem here. Any chance of a step by step reproduction please? - Pauli

Re: WP 34S - indirect addressing issue Message #4 Posted by Paul Dale on 22 Jan 2012, 5:39 p.m., in response to message #3 by Gerson W. Barbosa You are correct. I tested in v3 which this is all working happily. The proper solution is to upgrade ;-) I've committed a fix. I don't know when the next v2.2 build will occur. - Pauli

I could do one this week if someone can point me to the fix. I've yet to patch to serial port fix into 2.2 as well.

I can confirm an error for version 2.2 1789 (emulator) where this returns 2. The same works fine in version 3.0 2289 (also emulated). Here it returns 1, as it should. Dieter

Re: WP 34S - indirect addressing issue Message #9 Posted by Gerson W. Barbosa on 22 Jan 2012, 5:46 p.m., in response to message #8 by Dieter I was having trouble in a program that worked on the HP-42S but would not work on my outdated WP 34S. Mine was flashed last July. Just received Eric's overlays (very nice on the former 20b!). A suitable USB-to-serial converter is still missing though. Cheers, Gerson. Edited: 22 Jan 2012, 6:03 p.m.
