Produce a report. This PROC REPORT step produces a report on grain production. Each BY group produces a page of output, so ODS creates a new body file for each BY group. The NOWINDOWS option specifies that PROC REPORT runs without the REPORT window and sends its output to the open output destination(s).

proc report data=grain_production nowindows;
   by year;
   column country type kilotons;
   define country  / group width=14 format=$cntry.;
   define type     / group 'Type of Grain';
   define kilotons / format=comma12.;
   footnote 'Measurements are in metric tons.';
