>Hello,
>
>We are using Visual FoxPro 5.0 and we are making a framework. For our security form we have put an index with a primary key on the 'username' field. The problem is that if we delete a record using the delete-command the primary key still prevents us to make another record with the same username. Is there a way to exclude deleted records from the primary key? Thank you for your time.

It's indication that primary key should be just sequential (surrogate) number having nothing to deal with deleted/non-deleted issues.
