Define the across variable. PROC REPORT creates a column and a column heading for each formatted value of the across variable Department. PROC REPORT orders the columns by these values. PROC REPORT also generates a column heading that spans all these columns. Quoted text in the DEFINE statement for Department customizes this heading. In traditional (monospace) SAS output, PROC REPORT expands the heading with underscores to fill all columns that are created by the across variable.

   define department / across format=$deptfmt. '_Department_';
