Tab Order and ID Order
The tab order is the order in which controls are described in the program’s Screen Section that matches with the order in which they get the focus when the user press the Tab button on the keyboard. This ordinal number allows you to identify the control via the CONTROL-VALUE data item. Every control has a ID property. The ID is a unique number that allows you to identify the control via the CONTROL-ID data item. See SCREEN CONTROL for more details about CONTROL-VALUE and CONTROL-ID data items.
