Create the data component. This DATA step does not create a data set. Instead, it creates a data component and, eventually, an output object.

The SET statement reads the data set Grain_Production. The WHERE statement subsets the data set so that the output object contains information only for rice and corn production in 1996.

data _null_;
   set grain_production;
   where type  in ("Rice", "Corn") and year=1996;
