Re: How to append prgs. to existing prgs without key in them?

Hello friends, thank you all for your hints an remarks! I was able to append two programs into one file and to load more files from the USB-drive into the program memory of the DM42. I thought, I communicated that in my last post, but your reactions show afterwards that I overestimated my knowledge ...

Re: How to append prgs. to existing prgs without key in them?

Hello all, @grsbanks: thank you for your hint. The fact is if I loaded two raw-files, at first I only see the last programs which are loaded at last, if I key in "shift" + "program". Since the two raw files ended with "END" and ".END." like @IonX: pointed out, you can only see in "program"-mode, tha...

How to append prgs. to existing prgs without key in them?

Hello all, the headlines shows what I don't know. I've tried to load a program to existing programs via USB-file, because I'm a lazy-bone. The new programs are in memory, but the older ones are gone. Of course there is a working around, I store the older ones translate them into clear-text, append t...

Cornu Spiral (Fresnel integrals)

Hi folks, I'm very fond of that machine. One half of the Cornu spiral! The other half you can get by mirroring the displayed one at lower left corner of the display. What does this little pic on the display for our calculator means? It has to do a lot work. The parameter t is in [0 ; 5] by 0.02 step...

definite integral competition between HP50g a. DM42

Hello folks, and the winner is.... ahh, I not like to spoiler the result. What was the job of the competitors? a) Of course numerical, because the hp50g lives in both worlds, the dm42 is only working with numbers. b) The Fresnel-Integrals have to be calculated. c) as pair on the stack y-stack has th...

Re: New Owner DM42

Hello all, @grsbanks: I tried the conversion from raw to txt with free42 and I was successfull. Now the strings are surrounded with quotes. But there is a little triangle in front of the keyword LBL.
