If necessary I lock records in Stock tables. At saving time I copy the cursor to the actual detail table. Except for the BEGIN TRANSACTION, END TRANSACTION and ROLLBACK, you do not even need a DBC. Due to the fact that to my knowledge there is no way to subclass a column, I have not found how I can ameliorate this markedly in VFP. Marc .
