Variables
Twenty-six variables named A
to
Z are provided
as
a standard feature
of
the
computer and calculation results and numeric values can be stored in these
variables. These variables have already been used for manual calculations, and
they will serve
as
"memories" when the computer
is
used
as
a calculator.
Capital alphabetical letters A to Z are used for variable names and these will be
called simple variables.
Subscripts in parentheses such
as
A(3) and X( 4,
5)
can
also be added
to
the variable name. Variables in this form are called array
variables and are used when handling large volumes
of
data.
All
of
the variables mentioned
up
to
this point are for numeric values and are
called numeric variables. Variables
to
which character strings are assigned are
called character variables. Character variables are indicated by adding a dollar
sign
($)
after the variable name such
as
A$. Character variables can also be used
as
array variables such
as
C$(12). In addition
to
these variables, the computer
is
provided with the exclusive character variable $.
In other words, the computer
is
provided with the following variables.
Simple variable Array variable
Numeric variable
A,
B,
C···,
z
A(O),
X ( 2, 2) · · · · · · · · · · · · · · · etc.
Character variable
A$,
B
$,
...
z
$'
$
A$(0),
X $ ( 2,
2)
· · · · · · · · · · etc.
The numeric variable will store numeric values
of
up
to
12 digits
(I
2 digits for
a mantissa and 2 digits for an exponent)
and
the character variable will store
character string
of
up
to
7 characters. The exclusive character variable $ will
store character string
of
up
to
62 characters.
< Two
Array
Declarations>
This computer
is
capable
of
array variable declarations
by
DIM
statements and
array declarations
by
DEFM
statements. By using a
DIM
statement, it
is
possible
to
use array variables
of
up
to
three dimensions. The
DEFM
statement
is
used
when desiring
to
expand the number
of
variables
but
it can also be used
to
declare array variables. A maximum
of
up
to
eight array variables can
be
used
simultaneously
with
a
DIM
statement.
