The Command
Instruction
Defined Keys may
be
specified in any
of
the Operation Modes
(RUN,
PRO,
or
RESERVE).
If
you
are using the Computer
by
itself (e.g., the Computer
is
not
connected
to
the Printer/Cassette Interface)
and you press
(ill)
0:0
(CSAVEj,
(ffi)
OJ
(CLOAD),
or
(ffi)
CQ) (MERGE), the Computer
will
display
"~".
This simply tells
you
that
the command
you
specified cannot
be
used because the Interface
is
not
connected.
Once the Interface and Computer are connected, however, you
can
specify these commands
even
if
the Interface
is
not
connected
to
a Cassette Recorder.
The second set
of
Definable Keys allows you
to
begin program execution at a
maximum
of
18
different
program
line numbers.
The
first
step
is
to
"label"
a program
by
specifying one
of
the allowable keys in the
first
line
of
the program.
To
do this:
1.
Type
the
program line number.
2. Type a
quotation
mark
(").
3.
Type
an
allowable key
(see
Table 2).
4.
Type
another
quotation
mark
("
).
5.
Type
a program
instruction.
