>I have a file that has several duplicate name in the file. I remembered you could index the file with a command like INDEX on Contact_name to t Unique.Which would index all records on the field Contact_name. But how do I extract/copy the unique records out of the file?

To get a set of records where all contact_name are unique:

select * from contacts group by contact_name into cursor crsContacts nofilter

You could of course add an ORDER BY clause to that as well.

Do you think you could extract out Scott Gomez and a couple other players and transfer them to the Dallas Stars roster list? < bg >
