Explanation
Example
DIM <variable>(<subscript >)[,< variable >(<subscript>)] ...
DIM <variable>(<subscript >, <subscript > )[, < variable >(<subscript>,
<subscript>)] ...
The DIM statement declares arrays with from one to four dimensions and reserves
space in the memory for the number of dimensions declared (DIM: DIMENSION).
Up to two alphanumeric characters beginning with an uppercase character can be
specified for <variable> as the array name, and subscripts of any value may be
specified to define the size of dimensions; however, the number of dimensions which
can be used is limited in practice by the amount of free memory space available.
Different names must be used for each array which is declared; for example, the
declaration DIM A(5),A(6,3) is illegal. Execution of a DIM statement sets the values
of all elements of the declared arrays to 0 (for numeric arrays) or nulls (for string
arrays). Therefore, this statement should be executed before values are assigned to
arrays.
If the DIM statement is executed on an array which has previously been declared,
and if the newly declared dimensions are greater than the existing array, an error
results,
All array declarations are nullified by execution of a CLR statement or a NEW
statement.
TO DIM AlSD ccosnenvcarsnesaccees Declares 1-dimensional numeric array A with 4

elements.

(2+1)x (3 +1)=12 elements

40 NEXT J

Three array variables (A(0), A(1), and A(2)) are used in this example. The program
inputs three numbers into these variables, then displays these numbers.
