>i am using databuffering and all works well except when i append a record (and do not move the record pointer) a new record in added to the table. According to the book a -1 record (buffered record) should be added which will be removed when i do a tablerevert() and will only be added if i do a tableupdate().

Are you using table or row buffering? -1 will be assigneg only in case of table buffering.
