Many thanks...

>Visual FoxPro keeps changed (and new) records in a buffer. New records have negative numbers (recno() returns "-1" for the first record the user adds, "-2" for the second, etc.). Definitive (positive) values for recno() are available only after the record is successfully saved with TableUpdate().

>You can either try to save all new and modified records (HELP TableUpdate()), or, if you feel the need to do this, save one record at a time (HELP GetNextModified()).
>
>You can also test whether the current record is modified, new, or unchanged (HELP GetFldState()).

>>I see, but in that case, can i APPEND BLANK to add records to the tables? How does it know how many to rollback?
