BOR (Beginning of Recordset) is true when the Recordset object is created by the  Command.Execute call, after the First method is called, and when the first record is reached by calling Prev when the cursor was on the second record.

If BOR is true and EOR is false, the cursor is pointing to the first record. If both BOR and EOR are true, there are no records in the Recordset. The Position is 0 in both cases.
