•.
The
DIM
statment allows you
to
explicity specify
the
size
of
arrays. The syntax
of
the
DIM
statement
is
as
shown:
DIM
array-name (rows
[,columnsl)
[,array-name
(rows
['columnsl)J.
••
where:
array-name
is
an arithmetic
or
character array
to
be
dimensioned.
rows, columns are nonzero, unsigned integer constants specifying
the
dimensions
of
the
array. One-dimensional arrays require only
the
rows entry. Two-dimen-
sional arrays require both rows and columns entries.
A one-dimensional array whose name
is
specified
in
a
DIM
statement
is
defined as
having
the
number
of
elements represented by the rows entry. A two-dimensional
array whose name
is
specified
in
a
DIM
statement
is
defined as having
the
number
of
rows and
the
number
of
columns entered
in
the
statement.
The initial value
of
each arithmetic array element
is
zero; each character array element
is
18 blank characters.
Notes
About
DIM
•
An
array name cannot appear
in
a
DIM
statement
if
it has been previously
defined, either implicitly
or
explicitly
in
a
USE
statement
or
a prior
DIM
statement.
• An arithmetic
or
character array
of
one
or
two dimensions can be defined
in
a
DIM
statement.
• The maximum permissible size
of
each dimension
in
an array
is
255.
