Re: Things to improve on the hardware

On the issue of screen glare. By chance I came across a matte screen protector for a kindle ereader. Cut to size it makes a good improvement to the readability of the screen.

The unused top function key

How hard would it be to make the unused F3 key a single press shortcut to the custom menu? Or is there a plan for it in the pipeline? Even better but harder to implement would be to make it universally assignable to any function, program or variable I like.

Call a catalogue menu from inside a program?

It crosses my mind that it would be nice to be able to call a catalogue menu, e.g. programs, from within a program. It would help, with say DPLOT, to save having to type the function name. Inbuilt programs like solver and integration are able to do this already for programs and I can think of other ...

Re: Alpha font ties to Last x

Super. This is why the DM42 is such an amazing piece of kit. You know that it is pretty close to perfect, when that is all there is to complain about. I guess you already know that the problem was slightly misreported, as the font size of the T register also impacts the font of the Alpha register.

Alpha font ties to Last x

It seems that the font size of the alpha register is tied to the font size of the Last X register, when the screen is in XYZTL mode. Is this a bug? Its not a train smash, but it does mean that my most preferred display mode with large X, Y and messages, but smaller ZTL registers is not available. Se...

Foating point bug

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...

Re: Adding elements to matrix programmatically

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?

Re: Constants

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...

Re: Txt to Raw and Raw to Txt

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.

Re: Wishes for next Updates

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...
