Array
Declaration
with
a
DIM
Statement
>
This
computer
is
capable
of
declaring
array
variables
of
up
to
three
dimensions.
These
array
variables
consist
of
two
types
which
are
the
character
array
variables
and
the
numeric
array
variables.
1)
Declaration
of
one-dimensional
array
variables
A
DIM:statement
is
used
to
declare
array
variables
and
a
one-dimensional
array
variable
will
be
specified
as
follows.
DIM
A(1@)
|
*The
numeral
10
in
parenthesis
is
called
a
subscript.
|
There
are
11
elements
in
this
array.
consisting
of
A(O),
A(1), A(2),
...
ACO).
:
These
array
elements
exist
independent
of
variables
such
as.A,
B, C,
etc.
|
which
are
numeric
variables.
A
CLEAR
statement
or
ERASE
statement
is
therefore
used
when
clearing
these
arrays.
When
declaring
two
array
variables,
punctuate
the
array
variables
with
a
comma.
DIM A(3),B(3)
| 94
5-3 Variables
We
can
then
use
array
variables
such
as
A(0)
A(1)
A(2),
AG),
B(O),
B
>
zy
>
fy
9.
>
For
a
character
array
variable,
add
the
symbol
§
after
the
variable
name.
DIM A$(4)
This
declares
the
array
elements
A$(0),
AS(1),
...
A$(4)
as
the
character
array
variables.
2) Declaration of two-dimensional array variables
When
declaring
two-dimensional
array
variables
with
a
DIM
statement
punctuate
the
subscripts
with
a
comma.
DIM A(2,3)
The
array
variable
is
now
declared
in
two-dimensions.
There
are
12
array
elements
as
shown
in
the
table
below.
y -
A(0,
0)
A(0,
1)
A(0,
2)
A(0,
3)
x
A(1,
0)
A(1,

A(1,
2)
A(1,
3)
A(2,.
0)
A(2,

A(2,
2)
A(2,
3)
For
a
character
array
variable,
add
the
symbol
§
after
the
variable
name.
As
in
the
case
of
one-dimensional
array
variables,
multiple
array
variables
can
be
declared
at
the
same
time
by
punctuating
with
commas.
3) Declaration of three-dimensional array variables
Punctuate
the
subscripts
with
commas
similar
to
when
declaring
two-dimen-
sional
array
variables.
DIM A$(1,2,3)
Array.
declaration
is
in
three
dimensions
with
character
array
variable
A$.
There
are
24
array
elements
(2
x
3
x
4)
and
since
they
exist
independent
of
the
character
variable
A$,
the
contents
of
the
array
variable
remains
un-
changed
regardless
of
what
is
substituted
for
A$.
Similar
to
the
one-dimen-
sional
array
variable,
it
is
possible
to
declare
multiple
array
variables
at
the
same
time
by
punctuating
with
commas.
