I have three permanent constants in this catagory.
"pi", "n", and "e".
They don't get deleted like all the other user entered constants when I exit graphcalc.
I like this feature for "pi".
Where are these values stored and can I modify
this list of "permanent" user entered constants?
I don't know where these constants are stored, but if you want to modify them, the easiest way is perhaps to write a little script, to redefine the needed variables.
This script could be executed automatically after the start of the program (see under Options -> Program Options -> Startup Script -> Enable and enter your script name)
In the script file you enter all the things you needed. My file contains:
q=(Physics|electron charge (C))
u=(Physics|atomic mas unit)
h=(Physics|Planck constant |-|h (J s))
I hope, I could help you with this.
That works fine. I'm still curious about the location
of the pi, e, and n, constants listed as user entered. They seem to be permanent.
