>>>>>>>>Hi everybody,

>(1) there are no vfp statements (ie the whole scan loop that is done 3 times) to process, hence faster
>(2) there's no &processing, hence faster

1) Select-sql will make the same number of scans (joins) as in my code
2) in regard to '&', well it is too old. Please, be assured that if I would spend more than 5 minutes writing it, then I could easily eliminate '&' just to please you.
