However, you need to declare an array before you can use them. You can declare a variable with the Dim statement, using commas to separate multiple declarations. To declare a variable type, enter a type-declaration character following the name or use a corresponding key word.</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="27" xmlns:help="http://openoffice.org/2000/help"/><help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> Basic supports single or multi-dimensional arrays that are defined by a specified variable type. Arrays are suitable if the program contains lists or tables that you want to edit. The advantage of arrays is that it is possible to address individual elements according to indexes, which can be formulated as numeric expressions or variables.</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="28" xmlns:help="http://openoffice.org/2000/help"/>Arrays are declared with the Dim statement. There are two methods to define the index range:</p>

<p class="Paragraph"><help:paragraphinfo state="U" number="35" xmlns:help="http://openoffice.org/2000/help"/>You can declare an array types as dynamic if a ReDim statement defines the number of dimensions in the subroutine or the function that contains the array. Generally, you can only define an array dimension once, and you cannot modify it. Within a subroutine, you can declare an array with ReDim. You can only define dimensions with numeric expressions. This ensures that the fields are only as large as necessary.</p>
