Of course it doesn't. Why would you expect STO arithmetic to change LASTX since the value in X is unaffected ?

That's quite right, and I wasn't expecting it to. My posting was a reply to Thomas Okken's post in which he wrote, "RCL arithmetic affects LASTx, while STO arithmetic does not." Since he wrote this about the HP-42S, I extended his observation to the other models.
