RESERVE
Mode
To
enter the
RESERVE
Mode, press (SHIFT)
(MODE)
.
RESERVE
will
appear on the Display.
In
this
Operation Mode,
you
can
assign
commands, statements,
or
values
to
any
of
the
Function
Keys (
CID
~
CEID
) in any
of
the three Reserve Modes (I/II/III)
for
a
total
of
18
different
Function
Keys.
To
go
from
one
Reserve Mode
to
another, press CIJ and the Display
will
change
from
I
to
II
to
III.
For instance,
CID
can
be
assigned one value in Reserve Mode
I,
a
different
value in Mode
II,
and
still
another
value in Mode
III.
To
use
a
Function
Key
which
has
two
or
three values,
press
CIJ
to
change modes, then press the appropriate
Function
Key.
Any
value, statement,
or
command
which
the
PC-2
recognizes
can
be
assigned
to
a
Function
Key.
You'll
find
it
most convenient
to
assign
common
command statements (such
as
RUN
or
TIME)
which
you
might
use
very
frequently.
You
might
also
assign
long mathematical
functions
or
command lines
to
a key. Then, instead
of
typing
them
over and over,
just
put
the
Computer
in the appropriate Reserve Mode and press the proper
Function
Key.
The
value assigned
to
a
Function
Key can
be
any
number
of
characters in length
up
to
a
maximum
of
77.
However,
the
total
number
of
characters
for
all
18
Function
Keys
cannot
exceed 77. When the
maximum
number
of
characters
is
reached,
Error
13
will
result.
Press
(ENTER)
. The value
will
be
assigned and the PC-2
will
return
to
the
Ready
prompt.
