Although you can change the size of an array during program execution, its configuration
cannot change. For example, a two-dimensional array cannot be changed to
one-dimensional and vice versa.
Examples
In the following example, the program statement creates three arrays: one-dimensional
NAME, one-dimensional TITLES, and two-dimensional DATES.
DIM NAME(100),TITLES(100),DATES(100,2)
In the next example, two DIMENSION statements are included in the same program,
although because the new array is smaller than the original, all excess data is placed
in element 0,0. After the execution of the second DIMENSION statement, the array
has the dimension of 100 by 10.
DIM WAGES(50,100)
DIM WAGES(100,10)
The following program segment creates the array TEST by setting variable A to 30,
and then declaring TEST as a one-dimensional array of 30 elements:
A = 30
DIM TEST (A)
The following sample code is invalid because array size is declared with nonnumeric
variables “(” and “)” and because you cannot use a variable in a dimension statement:
TEST = "(10,5)"
DIM TEST
In contrast, the following statement is valid:
DIM TEST (10,5)
