I forgot to mention:

You can easily get each field from the record using
sequence slices. If each record has 2 fields: NAME
and LAST_NAME of length 50 each, the earlier
example can get each fields with

name = record[1..50]
lastname = record[51..100].

The use of this kind of database file, as opposed to
sequence-based, allows the data to be easily read
from other programming languages (like Pascal, C,
or Basic).
