4-3 Variables
We can then use array variables such as A(O), A(l), A(2), A(3), B(O), B(l),
B(2), B(3).
For a character array variable, add the symbol$ after the variable name.
DIM A$(4)
This declares the array elements A$(0), A$(1 ), ... A$( 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.
(
~ ~
A(O, 0) A(O, 1)
A(O, 2)
A(O, 3)
y
x
\
A(l, 0) A(l, 1) A(l, 2) A(l, 3)
A(2, 0)
A(2, 1)
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.
