Re: DM42 Programming Tool bug

According to HP-41 Synthetic Programming Made Easy by Keith Jarett, the third byte of an END can have four values: 09 = packed END, 0D = unpacked END, 29 = packed .END., and 2D = unpacked .END.. The low nybble of the first byte and all of the second byte encode the offset to the next item in the glo...

Re: TVM for NSTK mode

Ugh, no, ignore my previous post. I was talking about the programmable menu (CLMENU, KEYG, KEYX, MENU) while the topic at hand was of course VARMENU / VARMNU1. I did say one thing in that post that is relevant to your question, and that is that RTN is the way to get out of this situation as well. It...

Re: TVM for NSTK mode

Hmm, I am stuck in a menu loop! What would be the idiomatic way to allow the menu to escape? Does it put a key '9' anywhere I can check on? Use RTN; that not only clears the RTN stack but also exits the programmable menu without tripping the EXIT handler. Also, when creating a programmable menu, al...

Re: TVM for NSTK mode

Nice! I'm glad to hear that solved the problem. As far as starting guesses are concerned: I'm not really all that knowledgeable about the topic either. Most of the Plus42 TVM functionality is pretty straightforward and was derived from the equations given in the HP-17B manual, but of course I%YR is ...

Re: DM42 Decoder

I posted new text<->raw conversion tools, raw2txt and txt2raw . They are under Additional Downloads on the Free42 and Plus42 home pages. These tools are based on an idea by Thomas Klemm, to simply use the Free42 / Plus42 core itself to do the conversions. The resulting executables are a bit large, b...

Re: German Format

Nimm es Walter nicht übel, er ist halt so. :-D Die Einstellung des Dezimaltrennzeichens lässt sich ändern mit den Funktionen RDX. und RDX, im DISP-Menü, und die Datum-Anzeige lässt sich ändern mit den Funktionen MDY , DMY , und YMD in der dritten Reihe des MODES-Menüs. Willkommen im Forum! Ich würde...

Re: DM42 Decoder

Here is a DM42 Decoder. It can decode the modified stress program attached. Now that you mention it, the stress program on my web site is way out of date, since it only covers the HP-42S instruction set. I just uploaded a new version, including all the additional functions from Free42 and Plus42. T...

There's a slight fudge in that the START/END button often needs a second press to get it to switch modes.
You can fix that by using VARMNU1 instead of VARMENU.

Ok you'll have to tell me what you think of my TVM program!
Ask me again after I get my next release out the door. :-)

Re: Possible to replicate varmenu behaviour with menu?

The number input flag, flag 22, is set when any of the number keys (0-9, E, period) are pressed while in RUN mode. The flag stays set until explicitly cleared using CF, FS?C, or FC?C. That's really interesting - so I think you're saying it works on a per-program basis? So it starts off cleared at t...
