Type Help Tree and scroll to About HP Prime and hit Enter. The serial number is the same as the one on the back of the calculator.

#13

No, there is not at this point.

So, is there some sort of different serial number than the one that is reported in the About HP Prime screen ?


#15

No, there is only one as far as I know. I was quite pleased too when I discovered the outside matches. :-)

The question seemed to be if there was a *command* to get that number similar to the SERIAL command on the 50g or something the way I read it.

Thank Tim,

Your and Cyrille´s answer help a lot,

I offer as gift some programs, but I want to protect my programs to let only allowed user to run it. I tought to create a library with serial encripted inside (as some hp 50g programs does), then send to allowed user´s calcs, once the programs execute it will check the serial if match the continue execution. But if no command for reading the serial it is very difficult to do.

Do You have and idea how to do it ?

Thank you so much.

Best regards!!

Well, there really is no way to do that at this point for the simple fact that a prime program consists of the source, and no compiled binary. There is currently no way to package a binary up and not included the source as well.

Thank You Tim,

I will wait to see any evolution that help to protect libs.

I never knew there was such a command on my 50g. I just checked and the S/N differs from the label on the back. It suggests an earlier date code, CNA 717... .vs. CNA 720... Any significance ?

No significance. They are often several weeks apart. I have two 50g's right here whose stickers only differ by 4 (same week!), but whose internal serial numbers are 7 weeks apart. Check it out:

EXTERNAL -- INTERNAL
6432048 -- 6334082
6432052 -- 6402026
