Hi Fabio,

VFP does not read individual fields from disk. The minimum block it reads is a record, but, usually, it reads several records at once and puts them into file cache. The read operation occurs when VFP navigates from one record to another and not when field values are queried. You have to reread the record to get its most recent state.

Thanks,
Aleksey.
