This BREAK statement produces a default summary after the last row for
each manager. OL writes a row of hyphens above the summary line. SUMMARIZE
writes the value of Sales (the only analysis or computed variable) in the
summary line. PROC REPORT sums the values of Sales for each manager because
Sales is an analysis variable used to calculate the Sum statistic. SKIP writes
a blank line after the summary line.
