Re: (SQRT 0 1i ) ^2

Nice finding ! This is a minor Free42 accuracy flaw: Doing SQRT( 0+1i ) is giving: 0.707106781186547524400844362104849 0 + 0.707106781186547524400844362104849 1 i Since the real and imag parts are not equal (as they should be), squaring back this number doesn't give exactly 0 for the real part. Ind...

Re: SOLVE reentrancy

You're not wrong. You can't use SOLVE recursively. You can SOLVE an INTEG, or INTEG a SOLVE, once, but not SOLVE a SOLVE or INTEG an INTEG ;-)

Re: Does DM42 support HP-41 synthetic functions?

X<> d is a synthetic function alright, and no, the 42S and Free42/DM42 do not support these. In this case, you may use the RCLFLAG and STOFLAG functions instead, though not in the same way.. there's no X<>FLAG functionality - the 42S has more flags than fit in a single register. See https://thomasok...

Re: DM42 / Free42 state file compatibility

Do all keyboards have the € symbol? Can't say, as here (in the EU in general) it is normal for all keyboard varieties to have it. I also wouldn't know of any other character that is not on the 42 yet on all keyboards.

Re: DM42 / Free42 state file compatibility

Too bad HEXM is a setting that is only used within the BASE application - setting 'hex mode' could otherwise be used to show XSTR entries as hex codes, and export a program in readable format.

Re: DM42 / Free42 state file compatibility

Question: it's only the first text character that determines whether it's a string or an alpha command, right?
So if I have a string with a first character < 128, but possible larger codes further down, that will always be recognized as a string?

Re: DM42 / Free42 state file compatibility

XSTR, yes. Once it finds its way into the DM42 ;-) (!!!!!!!! it is there! I thought it was only in the latest release, along with all the other string functions. Yes, that's what I'm going to use, thanks! Even if I will have to do it all on the DM42 instead of the decoder) Thanks for considering the...

Re: DM42 / Free42 state file compatibility

I made an 8x5 font (digits only), and to be able to store it as a file, I created a program that creates the matrix. I had the luminous idea of using the DM42 encoder's hex editor to just create the necessary strings, and ASTO ST X \-> to save them in the matrix (using nnn XTOA would make the progra...

Re: DM42 / Free42 state file compatibility

there's been a state file format change between 3.0.5 and 3.0.6 And encoding, perhaps? I noticed by chance that the two program lines STOx "ABCD" and the one created with CLA 132 XTOA +"ABCD" @ (why can't the append character just be a '+' instead of the '|-' kludge?) A2LINE are...

Re: Matrix Viewer

Hi, thanks for the nice words! It's been a while, and it was really only a 'Proof of Concept', to see if it could be done, and if the 'scrolling' was not too slow. I'm not sure which subroutines are used in the program.. M0N and Mx+ surely, maybe MANT or SMX, D44? you can quickly tell SST'ing throug...
