The DAT A BANK can hold all your
private memoranda such as names,
telephone numbers, addresses, dates,
etc. The object data can be speedily
retrieved from the large amounts of
stored data without the need for a
special program. Furthermore,
combined with a BASIC program,
you can use this function for an
expansive range of duties such as
schedules, totalizing, etc. The use
of the DATA BANK function is
explained together with actual ex-
amples. For details on the exclusive
commands (LIST#, RESTORE#,
READ#, WRITE#) for the DATA
BANK, refer to Chapter 6 "Com-
mand Reference".
