Methinks?

>First, a LOCATE command based on ALLTRIM() will not be optimized, since you will not have an index on ALLTRIM() (at least, I hope you don't - indices must be of fixed size).
>
>Second, in general, the SEEK command or the SEEK() function will be much faster than any alternative which simply relies on VFP optimization. Methinks you already what you need with the index called "code" - use it.
>
>One more thing: don't use "select 6" - using the alias will be much more readable, and easier for maintenance.
