# TEST	Test of DB->get and DBC->c_get with set_recno and get_recno.
# TEST
# TEST	Populate a small btree -recnum database.
# TEST	After all are entered, retrieve each using -recno with DB->get.
# TEST	Open a cursor and do the same for DBC->c_get with set_recno.
# TEST	Verify that set_recno sets the record number position properly.
# TEST	Verify that get_recno returns the correct record numbers.
