with the command return list you can see how call the results
example
sum rgdpl
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
rgdpl | 152 4626.693 2138.292 1692.86 11167.49
return list
scalars:
r(N) = 152
r(sum_w) = 152
r(mean) = 4626.692887155633
r(Var) = 4572291.459771345
r(sd) = 2138.291715311862
r(min) = 1692.859985351563
r(max) = 11167.490234375
r(sum) = 703257.3188476563
