Explanation
- Header Record (HEADER): Printed at the top of each page, typically includes the report title.
- Detail Record (DETAIL): Contains the data for each record from your input file.
- Footer Record (FOOTER): Printed at the bottom of each page or at the end of the report.
Handling Page Breaks
Ensure that your report handles page breaks correctly by checking the line count and printing the header/footer as needed.
Advanced Features
- Grouping and Totals: You can add logic to group records by a certain field and calculate group totals.
- Conditional Formatting: Apply different formats based on the value of the data.
- Multiple Columns: Design your report to display data in multiple columns or tables.
