A HIGHLIGHT action attaches a display attribute (color) to a message. If you use this action with DISPLAY, you can highlight supplemental messages as well. Only one HIGHLIGHT action is allowed per operating mode. The actual appearance (color and format) of the text is controlled by view properties in OS 2200 Console View. The following list explains each attribute and its default value.
| Attribute | Default Color and Format |
|---|---|
| RED | Red, no format |
| GREEN | Green, no format |
| YELLOW | Yellow, no format |
| WHITE | Dark blue, no format |
| COLOR1 | Brown, no format |
| COLOR2 | Purple, no format |
| COLOR3 | Light blue, no format |
| COLOR4 | Black, no format |
See 4.2 for formatting information. The action-text is one of the attribute names from the above table.
