(On the HP-42S, at least -- I'm not familiar with how RCL arithmetic works on the other models mentioned earlier.)

It was fun checking these:
RCL arithmetic also DOES change LASTX on the HP 35s, 33s, 32SII, and 45 (and DM42 of course).
RCL arithmetic does NOT change LASTX on the 15C or 15C LE.
STO arithmetic does NOT change LASTX on any of the above models.
(I don't have any other models with recall arithmetic).
