Read Time: 1 minute(s)
BAR.CONTROL is used to define the behavior of several shop/floor and time and attendance procedures designed for use with bar code wedge devices. When using bar code devices it is sometimes desirable for the transaction to be saved automatically after the last bar code entry and to exit the procedure. You can set both of these parameters for each procedure defined.
