Release 10.1A: OpenEdge Development:
Progress 4GL Reference

> ## IMMEDIATE-DISPLAY attribute

> The frequency of screen updates for the current session.

> Data type: LOGICAL

> Access: Readable/Writeable

> Applies to: SESSION system handle

> If TRUE, Progress updates the display for every I/O operation, including DISPLAY statements. If FALSE, Progress does not update the display until a statement blocks for input, such as an UPDATE statement. FALSE is the default setting. A TRUE setting provides more accurate screen displays during long display loops at the price of slower performance.

> In Windows, this attribute has a similar effect on interactive I/O to setting the MULTITASKING-INTERVAL attribute to a low non-zero value, providing a more frequent display refresh. This attribute also provides the same functionality as the ImmediateDisplay parameter in the current environment (which might be the Registry (Windows only) or an initialization file). For more information on environments, see the chapter on user interface environments in OpenEdge Deployment: Managing 4GL Applications .
