Rulers

A ruler is a set of screen-editing rules that make a report look different when displayed or printed.

Rulers can be used to:

• Define headers
• Freeze report columns in place
• Re-position fields in the screen layout
• Eliminate unwanted or unnecessary fields from the display
• Select records for inclusion in (or exclusion from) the display.
• At sites with color monitors, rulers can also be used to color and highlight the displayed report.

In this exercise you will create a ruler that can:

• Identify report Header lines so that they do not scroll out of sight.
• Freeze the EMPLOYEE NO. and EMPLOYEE NAME fields in place so that they are visible even when the display is shifted to the right.
