·Clears the record buffers.  
·Sets the cursor to the end of the dataset file.  
·Fetches the last record, positions the cursor to it, and makes it the active record.  
·Fetches any additional records required for display, such as those needed to fill out a grid control.  
·Sets the Eof property to True.  
·Broadcasts the record change so that data controls and linked detail sets can update.
