when
one-dimensional
2)
Array name (i,
j)
when
two-dimensional
3) Array
name
(i,
j,
k)
when

Upper case alphabetical letters
may
be used for

Explanation:
1) Declares array variable names.
2)
Character arrays can
be
declared
by
attaching a $ sign immediately after the
array variable name. The storable character length
of
a character array
is
a
maximum
of
seven characters.
If
an
attempt
is
made
to
assign a character
string
with
more
than
seven characters, all
beyond
seven characters will be
disregarded.
3) The same array name can
be
used for a numeric array name
and
a character
array name.
4)
Up
to
eight arrays can be declared.
Error
1 will occur
if
nine
or
more are
declared.
5) Error 5 will occur
if
arrays are declared
with
the
same array variable name
and the different size (i,
j,
k)
of
the
subscript. When array variables
of
the
same size are declared,
contents
of
all array variables will become 0 or null.
