Question about Random Access files.....

I am trying to create an application that will write some records to Random Access file that will allow a field (a name) to be entered only once in the file.

Do I need to open the file twice: once to read and check the names; and once to write the name to the file if the name is not already there? (FileGet.)
FileGet(1, udtName, intRecordNumber)


Or will using the OpenAccess.ReadWrite argument do both:
FileOpen(1, filename.data, OpenMode.Random, OpenAccess.ReadWrite, _
OpenShare, Len(udtName))

So far not having much luck with either option.

Thanks
