'+' (Add Picture)

The '+'-operator can be used in combination with picture presentation commands. The current screen image will not be deleted and the new picture will be added to the image.

If you use this operator with the CS-command, the command does not clear the screen but waits for a given time interval. It also updates the color settings if it has been changed by a SC-command (Set Color) since the last visual presentation.

You cannot place a screen operator in front of a feedback action. To add feedback to the current screen, place a '+'-operator in front of a FB-command.
