Try this. The original link got mangled with extra http:// prefix

I tried out the program Moon, and it has a problem, as the HP Prime doesn't have a command atan3. Maybe it is just a small mistake, but what command was that supposed to be?

This is an inverse tangent function that yields correct results in all four quadrants. You need not look far for it because it is contained in the same repository from where you got the "Moon" program.

Hi,

May I suggest to upload these programs to hpcalc.org?

I checked there and looks like they are not there yet.

My guess is these programs are a little bit hidden only in this thread.

Thank you

Cheers
