A group of like, child widgets that are created within ASSIGN statements, one after the other in the program. You create a tab group so that the operator can move the focus from one widget in the group to the next (and wrap around again), without having to traverse every widget in the PANEL.
Only the widgets that have a TAB STOP attribute can be members of a tab group and can accept the system focus. Level-0 widgets cannot be members of a tab group.
A common example of a tab group is a row of buttons across the bottom of a PANEL. The buttons present the operator with a group of related choices, such as YES, NO and CANCEL.
