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.
