>I use clipper .dbf as a free tables in my application and create CDX files, In case my clipper application is still using that dbf, can I seek the record without reindex the CDX ? .. thank you very much

you can "SEEK" with clipper on a table indexed with a CDX and you do not need to reindex the CDX file.

i am referring to clipper 5.2
i do not know if previous versions of clipper support this ability
