The value
you
assign
to
variables
will
be
retained
until:
• NEW
or
CLEAR
is
entered.
•
The
values are changed
by
the
execution
of
a program.
•
The
variables are assigned new values.
Recalling Values.
Any
time
you
need
to
recall a value assigned
to
a specific variable
(A-Z),
just
type
the variable
(A,
for
instance) and
press
(ENTER)
. The value
currently
assigned
to
A
will
be
displayed
on
the
right
side
of
the
Display.
Another
way
to
recall a value
is
to
specify the memory storage location, using the @ sign.
For
instance,
type:
to
recall
the
value assigned
to
the
variable
B.
Recalling Equations. Once
you've
calculated the result,
you
may
need
to
recall the original expression.
To
recall
an
expression (when the result
is
still displayed), press
~
or
~
. The expression
will
then appear, ready
to
be
edited
or
changed.
•
If
you
pressed
~
,
the
Cursor
will
be
positioned
after
the
last character.
•
If
you
pressed
~
, the Cursor
will
be
on
top
of
the
first
character
of
the Display.
To
re-display the result,
press
(ENTER)
. Once you clear the Display, the original equation cannot recalled.
If
the
Computer
is
turned
off,
it
will
remember
the
values assigned
to
the variables
but
you
will
not
be
able
to
recall the expression itself.
