Release 10.1A: OpenEdge Development:
Programming Interfaces

Summary

This chapter showed how to write Progress procedures that produce both simple and sophisticated reports.

Generating simple reports

You can use the DISPLAY statement to generate a simple report output to the screen from a single table or from multiple related tables. You can easily format a report to group records and include calculations with the CONTROL BREAKS option and aggregate functions.

Redirecting output

The STREAM-IO option allows you to redirect the output of a report-generating procedure to a printer or text file. This option removes the graphical components of your data. You can also redirect output to multiple destinations, and you can define multiple streams.

Generating reports of data represented by widgets

The widgets that deal with text-fill-in field and text widgets-pose no special problems when you generate reports. However, you must make certain adjustments for widgets that represent data graphically. There are two ways to handle these widgets in reports:

Use the STREAM-IO option.
Use the PUT statement instead of DISPLAY. PUT suspends default frame-based formatting.

Customizing reports

You can customize your reports by:

Adding headers and footers.
Using advanced printing techniques, such as printer control sequences.
