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.
