Dear Sven,
Sorry I am not an expert on Gretl.
From the info you provided I now found in the info included with the
package how to select the R/S that is a default or the DFA algorithm.
So, I can get the Hurst from the menu item Variable > Hurst exponent.
Also, fro console by typing:
include gen_hurst.gfn
h_rs = gen_hurst(djclose, 0)
Also, I noticed that when I go to packages here:

and double click on the package I get a menu like this:

Is anywhere in the normal Gretl menu like the Variable > Hurst exponent
item?
Or I always need to go to packages and double click this?

I believe DFA is only (optionally) available in the gen_hurst
contributed package. R/S is available both in the native command and in
gen_hurst AFAIK.
So the hurst exponent I select from the Variable menu is different than
that gen_hurst?
If so, how do I run the gen_hurst one? I tried this and did not work:

I don't know what Anis-Lloyd is, so it could or could
not be implemented. But the native "hurst" command has a
relatively
detailed verbal description of what it does.
cheers
