Answer / abhinav
When you perform any db operation on a record within a set or an area, it becomes the reference point for further operation viz. obtain next.For an obtain next,you have to have a reference point from where the traversal can go forward.Currency is just that.
Currency is scope dependent.A record just accessed within a set becomes the current of that set,similarly a record accessed within an area becomes current for that area.
