If you're going to create and maintain a small database (I would say up to
100
records, but that depends on the size of the record), it much easier to just
print()
and get() your database as an Euphoria sequence. If the database is bigger
you
should load into memory only the record(s) that you need (using get() loads
the
complete file into memory!). Using seek() you can make your program to
position
the next-to-be-read-character pointer. where() tells you where is this
pointer
pointing.
