Yes for the stack and flags, but No regarding LastX. Which is not preserved – on exit it contains a complex number or a vector, respectively.

Well, that should teach me! I read a post claiming all was preserved and while I bothered to check the flags (by reading code) and the stack contents (by testing), and all was confirmed, I did not check the LastX and extrapolated it too was safe. Never, ever assume...

Thanks for this alternate version Dieter. For the 2nd time in a week, after not touching it for a couple years, I've decided to enter programs in my 35S. If I learned about how useful and well-behaved equations are on the 35S when I got mine in 2007, I've totally forgotten it, so Pauli and your programs are good examples of how this feature can be used to build well-behaved functions pretty easily.
