Re: Possible to turn off pixel?
Nice! Running it in Plus42, but with the display set to 30 rows and 67 columns (401x240 pixels) and using parameter block 2, the program finishes in about 6 seconds on my iPhone 13 mini. The only fly in the ointment is that pasting the program directly into Plus42 fails, in that the lines containing...

Re: Possible to turn off pixel?
I had discounted the AGRAPH approach because of the challenge of packing characters to generate graphics while plotting. You don't have to deal with packing characters. What I was trying to point out is that you can use AGRAPH to clear individual pixels, just like you can use PIXEL to set individua...

Re: Possible to turn off pixel?
As you have discovered, PIXEL only turns pixels on, not off. So AGRAPH is your only option for turning pixels off. Luckily, this isn't complicated: 00 { 18-Byte Prgm } 01▸LBL "PIXOFF" 02 SF 34 03 CF 35 04 "×" 05 AGRAPH 06 END Note that the character in line 04 is a multiplication...

Re: PIXEL bug?
I think PIXEL and AGRAPH, and LINE in Plus42, are useful in run mode, for checking parameter behavior (which I can never remember)... I’m not sure they are very useful on Free42 with the lower half of the display covered by the menu, and the upper half with the X content. You're obviously not going...

Re: PIXEL bug?
When the message flags are set, the display is not updated the way it usually is after a function completes. Whatever is there, stays there. That's why the PGM.FCN menu appears to stay up when you execute PIXEL using that menu. The menu is not actually active after PIXEL returns; it just looks that...

Re: how to read state file?
This should improve things a lot.... https://technical.swissmicros.com/decoders/dm42/ Unfortunately, it won't. That page only converts "raw" files to and from plain text, but grbrum was asking about state files. State files are in a binary format that wasn't designed to be human-friendly....

Re: PIXEL bug?
I don't know what exactly the DM42 does, but on the HP-42S and in Free42, PIXEL sets the pixel indicated by the coordinates in X and Y, and it sets the message flags . The part about the message flags is important, I did not just mention that in order to be pedantic. When the message flags are set, ...

Re: PIXEL bug?
Regarding the second part of your question: PIXEL sets flags 50 and 51, the message flag and the two-line message flag. That causes the display to freeze, until the user does something, or until the program calls CLD.
