This compute block executes at the top of each page, after PROC REPORT
writes the title. It writes the page header for the current manager's store.
The LEFT option left-justifies the text in the LINE statements. Each LINE
statement writes the text in quotation marks just as it appears in the statement.
The LINE statement writes a variable value with the format specified immediately
after the variable's name. The at sign (@) specifies the column to write in.
