You can set a screen update mode for a 4D Write area by using the command WR UPDATE MODE. This command only affects screen updates caused by 4D Write commands. User actions in the area will continue to update the screen correctly.
When screen updating is turned off, 4D Write commands execute faster. For example, if you intend to execute a series of modifications to a 4D Write area, turn off updating before beginning the modifications and then turn updating on when you are finished. The commands execute faster as well as the screen redraw.
WR UPDATE MODE (area; mode)
Set mode to 0 no updates and to 1 for updates.
