used

o
n,
the computer
will not treat it as a logical
equation
but
as
an assignment
statement for
variables.
When using an equal
(=)
sign for a logical
equation,
use
it i

the
form of "numeric value
=
A"
or·
"formula
=
B",
with the exception of
conditional expressions used in IF
statements.
Direct Calculation Feature
In the manual calculations described up to
now,
we always used
the
I
ENTER)
key
to
terminate a formula and obtain the calculation result of the
formula.
However,
you
can
directly operate the functions of the computer
with
the
desired
function key (without
operating the
I
ENTERl
key) when the objective
numeric
data is in the
display.

Equations composed of logical

can
take
on
the

in
the
following
table:
x

y
represent numeric

es.
"The
values of y and x are
stored in
variables
Zand
Y,
respectively.
Note:
For
coordinates
conversion,
the conversion
results are
stored in variables Z
and
Y.
Therefore,
the previous
contents of
Z and
Y (or 2$
and Y$) will be
cleared.
