di r(sum)

If you want to store it I would do so in a scalar. A variable 
would be inefficient as it usses too much memory and a local
is not so precise. The latter can be important as now you
are dealing with an extremely large number, which is where
precision can become an issue. Generally I would first 
create a tempname and use that tempname for the scalar to 
avoid any problems due to the fact that scalars and variables
share the same namespace:

tempname sum
scalar `sum' = r(sum)

Hope this helps,
Maarten
