It works.
I'm starting to learn gretl and I dont know how should I write "sintax"
-spss- (or script ¡?).
Thank's for the example.
Thank you very much.

 If I understand your question right, you can do something like
 <script>
 smpl sex=1 --restrict
 scalar gs1 = gini(y)
 smpl sex=2 --restrict --replace
 scalar gs2 = gini(y)
 smpl --full
 loop i=1..5
  smpl region=i --restrict --replace
  scalar gr$i = gini(y)
 endloop
 </script>
