A LOAD nonzero
entry
specifies
that
a saved file
is
to
be loaded from
tape
into
the
work
area.
Any
previous
contents
of
the
work
area (except
the
keys files) are
destroyed when
the
file
type
is
specified
as
BASIC, Df-TA,
or
SOURCE. If
the
new file
type
is
a KEYx file;
the
new key file
is
added
to
the
work
area
without
altering existing
work
area.
If
the
KEYS/KEYx files already exist
in
storage,
the
loaded KEYS/KEYx files will replace
the
old ones. A
copy
of
the
saved file
is
loaded into
the
work
area, and
the
following information
is
displayed:
• User specified file identification (if any)
• Number
of
contiguous 1,024-byte areas
of
storage
in
the
file
• Number
of
contiguous 1 ,024-byte areas
of
unused storage in
the
file
• First line number (for BASIC
or
SOURCE)
• Last line
number
(for BASIC
or
SOURCE)
• KEYx numbers (for KEYx file types)
•
Amount
of
unassigned work area remaining (in bytes)
If
the
new file
type
is
KEYx,
the
new key file
is
added
to
the
work area. If corre-
sponding KEYx files already exist in storage,
they
are replaced by
the
new keys.
For example, if a new KEY6 function
is
loaded from tape, it will replace
the
existing
KEY6 function.
Notes About LOAD
• File
type
KEYS (load all keys functions within
the
specified file)
is
invalid when
the
file
number
is
zero (LOADO).
• File
type
SOURCE (load a program
in
user source format from
the
specified
saved file)
is
invalid when loading from
the
keyboard (LOADO).
• When loading a general exchange (type 02) file, SOURCE
is
assumed unless
DATA
is
specified. This file
type
is
used primarily for
the
Communications
feature. Also see
Negative File Numbers
in
Chapter 4.
•
If
file
type
is
omitted,
BASIC
is
assumed
.if
loading from
the
keyboard, and
BASIC
or
SOURCE
is
assumed if loading from a saved file (depending on
the
type
of
file). In
the
latter instance, if
the
type
of
file
is
not
BASIC
or
SOURCE,
an error message
is
displayed.
• The format for entering
data
after a LOA
DO,
DATA
is
identical
to
data
in
a
DATA
statement.
LOADO,
DATA also provides automatic line numbering and
the
keyword DATA for each line. The display shows:
0010
DATA
./
'-
/
!
i
