Re: Benchmark Speed?

Calculators today are a lot faster than 50 years ago! And the DM42 runs somewhat slow in order to conserve the battery. Compare Free42 running on an iPhone, 64-bit code on a fast CPU; the numbers I get for those two benchmarks are 5,593,077 and 481,193. ¡Caramba! Any faster and that machine will gi...

Re: DM42- clock losing time

My test has run long enough to show results: DM42: 13 s fast after 88 h = 41 ppm HP-50g: 3 ¼ s slow after 50.3 h = 18 ppm The DM42 is a beta unit, SN 62. I do have a data logger recording temperature and humidity in the same room, so I could provide those numbers if necessary. I didn't keep track of...

Re: DM42- clock losing time

I certainly never bothered with CORRECT/SETAF/RCLAF on my HP-41CX, but those were also the days when I still used a mechanical wristwatch, so my standards of timepiece accuracy were not very high. Of course nowadays, I rely on my smartphone to tell time, and it synchronizes with time servers on the ...

Re: Thermal Paper?

HP sold both blue and black print paper, and the black usually provides much clearer and better contrast results, but often you can't tell which type it is, as the seller typically doesn't know. When in doubt, you can always try asking the seller to check. All it takes is to tear off a small scrap ...

Re: Feature requests

Whether auto-repeat is a good feature or not is subjective, which is why Free42 lets you turn it off. N.B. There are actually two types of auto-repeat in Free42: (1) the one on the ▲ and ▼ keys, which lets you step through programs and multi-row menus by holding down the key in question, and (2) the...

Re: Put, Get, Data Matrix

NOTE: EXITing or EXITALL from the INDEX function does not clear IJ. When accessing any of the ← functions, values of the matrix appear. I noticed that Pica used EDIT and INDEXEd the matrix in one of his programs. Perhaps he is aware of this feature. To experience this, INDEX a matrix. EXIT then acc...

Re: External stack

if I understand it correctly, this would make the coding of the calling program, which uses PGMSLV, dependant on the nameing and the count of the program FOO. Correct. There's no way around that. And -- as you already mentioned -- MVAR called in a program directly (RUN mode) will still "pollute" th...

Re: External stack

In this context I would like to suggest a "LMVAR" command, wich works similiar to the LSTO-command and would create variables which evaporize into thin air, when the program has ended. Would this be possible? Yes, that's possible, and you don't even need a new command for it. Say you have a functio...
