Bookmarking Rows
An application can use the Bookmark property to save the position of the current record and to return to that record at any time. When you open a Recordset object, each of its records has a unique bookmark. To save the bookmark for the current record, assign the value of the Bookmark property to a variable. To return to that record at any time after moving to a different record, set the Recordset object Bookmark property to the value of that variable.
The user may not be able to view the value of the bookmark. Also, users should not expect bookmarks to be directly comparable; two bookmarks that refer to the same record may have different values.
If you use the Clone method to create a copy of a Recordset object, the Bookmark property settings for the original and for the duplicate Recordset objects are identical and you can use them interchangeably. However, you cannot use bookmarks from different Recordset objects interchangeably, even if they were created from the same source or command.
