Member variable XbpCrt():asyncFlush Foundation

Determines the display behavior of text-mode output.

Attribute: EXPORTED
Data type: Logical (.F.)

By default the instance variable :asyncFlush has the value .F. (false). This causes an XbpCrt window to display its screen buffer when the operating system schedules a time slice for the screen update. This can lead to the effect that screen output does not become instantly visible when text-mode output functions are called repeatedly in very short intervals. If this effect occurs, :asyncFlush can be set to .T. (true) which causes the XbpCrt window to flush its screen buffer in a pre-defined interval so that output is forced to become visible.
