Free42 with big stack, test version

Well, yes. When you turn on the big stack, you get big stack behavior. That is different from four-level stack behavior. That's the whole point. The only way to be perfectly consistent with the four-level stack is to have a four-level stack, which is why that mode is still there.

The error messages not including the function name is consistent with every single other error message the HP-42S has ever produced. What do you expect Free42 to be consistent with?

Since the X register cannot be empty with the four-level stack, obviously you can never get an error message with CLX, there is always a number there to replace with zero.

Are you having difficulty grasping the equivalence between "level 1" and "X register", and "level 2" and "Y register"?

What are you even talking about? We've been discussing the behavior of the big stack in great detail here!

etc.

Which question would that be? I must not be paying attention?

The watch was said to be outstanding, but at the watchmaker the tester took a look at the movement and it was encased in a plastic spacer. Even if you never see it, the tester said, the fact that is there is a turn of.

I'm sorry but now you're really losing me. I guess I'd better not tell you about all the changes I've had to make to the Free42 internals in order to be able to implement SST→, LSTO, FUNC, and RTNYES/RTNNO/RTNERR. Even if you never see it or use those functions, the fact that those data stuctures exist must surely be a turn-off as well.

Kill it? Are you paying even the slightest attention to what I'm doing?
