The Flush method refreshes the screen display.

OpenROAD does not reflect any changes to the display, such as background color changes on the form or a field, until the currently executing event block completes. If you want the changes to be immediately visible, use the Flush method immediately after the statements that make the changes. However, be aware that making frequent calls to this method can be costly to performance.

You must call this method using the CurFrame system variable.
