Yes, sure, in a real program the first steps would be x=0? GTO 000.

I'm not sure if TI Calculator with AOS got the [LSTx] function.

Of course not. But that's not my question. The point is that on a TI you don't need all this. There is no need to use LstX or a dummy multiplication. I just want to know whether the proposed key sequence (without 1 x multipliation and without LstX) also works on the 12CP or not.

Does it?

What happens if you press 123 [÷] [x²] [√x] [=] ?
