dBase IV database not indexed dBase IV database not indexed paridin (Programmer) (OP) 12 Jun 17 16:31 I'm working with this legacy software for a client, the problem is I don't understand why the index is dropped after closing the database. Is it a bug? NO It's not a bug How can I prevent that?

Yes, if you close the table and reopen it then you also need to specify the index if you want to use SEEK again.
