Artemis doesn't use the global variables.  (Neither does Athena.)
When I started writing them, it seemed that it would be easier to keep
everything straight if I explicitly set kmin, kmax, etc. everytime I
called feffit(), fft(), etc.  And, as Matt said, Artemis is doing the
typing for you.

You can see how Artemis (or Athena) does its thing by looking at the
ifeffit buffer, which is the second option in the Edit menu.  This is
a running record of every command sent to ifeffit by the program.  You
can also have Artemis write the ifeffit script it would use for a fit
without actually running the fit.  It does this specifically for
people like you who might want to switch to the command line.

You should be aware that Artemis moves all data and feff files into
its working space, ~/.horae/stash/artemis.project.0 on unix,
C:\Program Files\Ifeffit\horae\stash\artemis.project.0\ on Windows.
If you use Artemis' script or cull lines from the ifeffit buffer, you
will need change the paths to all files with your text editor.

Good luck!
