summarize is used in two ways: For numeric fields, summarize will calculate a running total of the field. The on arguments then determine when the accumulated value prints. When the field prints, the running total is reset to zero. Where break will print totals under an existing colum

Break is a relative of header, or vice versa. It is the mechanism to print sub-totals for a group of items. The break reserved word is used on the parent or driver of the sub-totals. The best way to see how it works is to view an example:      Page 1 — break    Page 2 ̵
