Re: MVAR vs INPUT

OK. Thanks for the clarification. I had never even tried to STO or RCL a global variable with a menu open. I would just put in menu items for all the constants I might need, and then RCL and STO will work fine. Although STO is not needed to store into a menued variable. You are not limited to 6 vari...

Re: MVAR vs INPUT

Again, I'm not sure exactly what the problem is, but keep in mind that even if there is an MVAR statement in your program, the variable does not actually exist until something is stored in it. When writing programs, it is best to store a number- usually I put zero- into each variable before starting...

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...
