Yesterday my DM42, running FW version 3.10 hung up a couple of times within about 15 minutes, after running flawlessly for many weeks. I then went online and upgraded to version 3.11 and the problem has not re-occurred. I also found out about the issue with the newer version of the Intel floating po...

1. You can avoid the extra row by careful placing of the -> commands in your program, since that is what creates a new row when the last one is full.

2. Can't you create a new matrix using by placing the rows and columns in the x and y registers, and using the NEWMAT command?

Here is another way of doing constants. They are all in an nx2 matrix called Const. As the DM42 cannot import a matrix directly, the program generates the constants matrix. I usually edit it on a PC for ease of copying and pasting long numbers. There is a short wrapper routine at the end to index th...

You can also use the PC version of free42. It will export/import a program as .raw, and copy/paste from the display as .txt. The .txt will have line numbers that you can strip using an editor like geany.

Yes please. I will even appreciate an even bigger font, that uses the whole width of the screen to display a full length number. You are able to read the keyboard print though, aren't you? I can, but I would read and use bigger keys better. Being used to hp35s, when I first got the dm42, my first r...

If I may ask, why don't you (whoever the admin is) like these images on your server? They are not very big.

Hmm. Maybe I am a bit spoilt. I am now in a dilemma. E=mc^2 was going to be boring, on grounds of being so famous that it is commonplace. An RPN program listing was not pretty enough for my liking, so I compromised, but I guess it is a bit of a mishmash now. Maybe <<m c 2 ^ * E - >> as pure RPL shou...

I could. It would still be RPN, but I tried to stay true to the DM42.

So here are a couple more. I have included an inversion to show how the impression is often quite different. But you can always do it easily yourself in Gimp. The Chinese characters are wu-wei, the Daoist concept of getting things done naturally, with out scheming or manipulating. https://www.dropbo...
