WP 34S: trouble with CLSTK Message #1 Posted by Miguel Toro on 22 Oct 2011, 12:03 a.m. Hi, I noticed that CLSTK not only clear the stack, but also registers L and I, so LastX value is lost after performing a CLSTK. I have revision 1728 in my 34s and I am using revision 1747 on my computer. In both of them I see the same result. Of course, other calculators as the 42s or the 35s, preserve LastX after clearing the stack. Regards, Miguel

I admit I didn't use CLSTK for months - I take 0 FILL instead. But anyway, you found a real bug :-) Congratulations! We will take care of it. Walter

Re: WP 34S: trouble with CLSTK Message #3 Posted by Paul Dale on 22 Oct 2011, 3:08 a.m., in response to message #2 by Walter B More a lack of communication and inadequate command definition than a bug :-( The question being are L and I part of the stack registers or not -- they are intimately linked to them at the least. Anyway, clear stack no longer clears I and L. - Pauli Edited: 22 Oct 2011, 3:09 a.m.
