Returns a value that indicates whether a Recordset object supports bookmarks, which you can set by using the Bookmark property.
Return Values
The return value is a Boolean data type that returns True if the object supports bookmarks.
Remarks
Check the Bookmarkable property setting of a Recordset object before you attempt to set or check the Bookmark property.
For Recordset objects based entirely on Microsoft Jet tables, the value of the Bookmarkable property is True, and you can use bookmarks. Other database products may not support bookmarks, however. For example, you can't use bookmarks in any Recordset object based on a linked Paradox table that has no primary key.
