Re: Upcoming FUNC change

Actually, FUNC makes sense in a 4STK environment but much less so in NSTK, except to make cleanup (and LASTX restore) unnecessary. True, but I implemented FUNC before the big stack. And then there's the combination of FUNC and LNSTK or L4STK, to allow 4-level and n-level code to interoperate. The w...

Upcoming FUNC change

I am currently working on redesigning the behavior of FUNC. In its current incarnation, I think FUNC has two flaws: it's over-complicated internally, and it doesn't do a good job of protecting the caller's state in NSTK mode. In 4STK mode, I think the way FUNC currently works is fine. A function usi...

Re: Display updates while solving

It's mentioned in the HP-42S manual, page 186, "How the Solver Works."

Why bother about the .END. in the first place?
It just makes things a lot easier, both in terms of the calculator's internals and in terms of the user interface, if it is enforced that there is always at least one program in memory. And that's what the .END. is for.

Re: The unused top function key

I don’t quit the CUSTOM menu. The calculator does. In fact, the real problem is that this menu is not an application menu. It’s a function menu. So when the user calls another menu (like CLEAR or CONVERT), the calculator goes back to NO menu instead of CUSTOM. The best way to implement permanent CU...

Re: Plus42 features in dm42 anytime soon?

That's just the standard skin, with the display size set to something large. I'd say 28 ENTER 36 SETDS.

A bit pricey, and mapping the keyboard would be a challenge. But still. :D

Re: DMY Indicator misplaced in Settings -> Date DMCP 3.24

It's somewhat of a religious discussion... Is it, though? How does the frequency of people being confused and asking questions about this compare with people asking similar questions about the other menus? For reference, I've had zero questions asking me to clarify or change how the date and time o...

Re: DMY Indicator misplaced in Settings -> Date DMCP 3.24

It's bad design IMO. I understand the rationale; using a layout like the 4th row of the MODES menu takes up more space, so you wouldn't be able to fit all the functionality of the DM42 time configuration menu in a single row. But a button that indicates what mode you would switch to, without indicat...
