Re: My minor 35s modifications Message #36 Posted by Norris on 31 May 2007, 5:42 p.m., in response to message #34 by John
On the 33S, pressing STO, RCL, or LBL automatically toggles alpha mode. This mode only lasts for a single keystroke, because the variables and labels on the 33S are restricted to a single letter.
If you are entering equations, such as "A = B + C", then you have to hit STO or RCL before entering each letter. When you enter equations, the STO and RCL commands don't do anything except toggle the alpha mode. You can store brief text strings as dummy "equations", but you have to press STO or RCL before every letter; there is no "alpha lock" mode.
I believe the 32S and 32SII are similar, and the 35S probably is too. It sounds like the 35S may recognize two-letter variables and labels, but even in this case, there might not be a need for a dedicated alpha key.
