Using an index, a very select portion of a database can be formatted. The -B flag will enable the fastest throughput of records from the database. If this flag can be used, the dbvform generation is speeded up a great deal by internal record buffering. Note that no index can be used with record buffering, and that record locking is disabled. Adjusting the page lengths and widths can create some very desirable effects.
