Re: Size Error
Actually I've worked out what it means - the number of the first statistical summation register. Having it set to 88 when there are only 25 registers - I can see why that caused a Size Error! Only question then is how I did this by accident. ΣREG is on a second-row menu, and it requires you to key i...

Re: Size Error
You are a genius, thank you. It was set to 88. Set to 11 and now is working again. If you don't mind then I'd appreciate knowing What this value actually means and What I accidentally did to cause this (I had been adding stat data to get arithmetic mean when it happened but I'm pretty sure I didn't ...

Size Error
Sorry if this has been asked before but I could not search on "Size Error" as it says the term is too common. I have no idea how my DM42 got into this state, but any stats functions now fail with Size Error. I can't even clear the stat registers without this error coming up. I have deleted...

Change Auto-Power-Off Time?
Is the auto-power-off time fixed on the DM42, or can it be changed somewhere? Thanks.

Re: Having Trouble with User-Programmed Menus (Programming Query)
Brilliant! Thank you so much, I love this forum. When I first got the calculator I found programming it very complicated, so apart from using it as a 'straight' scientific, I haven't done much with it. I'm currently writing my own programming manual, really more of an idiot-aid, a few sheets of A4 w...

Having Trouble with User-Programmed Menus (Programming Query)
Hi, I bought my DM42 nearly two years ago but am only just progressing to some of the more advanced programming techniques. Not enough time to play with it unfortunately. I've used the term 'user' here to mean 'the person running a program I've written', even though this will usually be myself :D I ...

Re: What is saved as a 'State'?
Thank you. I did assume it wouldn't store/re-load the date and time as that would be Very Silly , but I wasn't sure if there was anything else that didn't get saved.

What is saved as a 'State'?
Just how much is stored in a State file please? Does it include the current values of variables, registers, stack etc? What about loaded programs?
Or maybe I should ask if there is anything that isn't saved?
Many thanks,

Re: Programmatically Preserving Last-X Stack Register
Very many thanks for the replies. If I use a register variable then there is no need to clear it, so this gets the code down to 3 lines, and either of these work. Assumes original input value is in R 00 : X<> ST L X<> R 00 X<> ST L or X<> R 00 X<> ST L X<> R 00 Edit: Actually I think this is better:...

Programmatically Preserving Last-X Stack Register
This is a question about programming practice/methodology. I have written a some programs which take a numeric input from the X-register and perform some function on it, leaving the result(s) on X (and sometimes on Y if two parameters need outputting). After the program has run, the Last-X register ...
