<p class="Paragraph"><help:paragraphinfo state="U" number="20" xmlns:help="http://openoffice.org/2000/help"/>In <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> <text:s text:c="" xmlns:text="http://openoffice.org/2000/text"/>Basic, you do not need to declare variables explicitly. 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="21" 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="22" xmlns:help="http://openoffice.org/2000/help"/>There are two ways to set the range of indices for arrays declared with the Dim statement:</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="23" xmlns:help="http://openoffice.org/2000/help"/>DIM text(20) As String <text:s text:c="" xmlns:text="http://openoffice.org/2000/text"/>REM 21 elements numbered from 0 to 20</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="24" xmlns:help="http://openoffice.org/2000/help"/>DIM text(5 to 25) As String REM 21 elements numbered from 5 to 25</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="25" xmlns:help="http://openoffice.org/2000/help"/>DIM text$(-15 to 5) As String REM 21 elements (0 inclusive),</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="26" xmlns:help="http://openoffice.org/2000/help"/>rem numbered from -15 to 5</p>
<p class="Paragraph"><help:paragraphinfo state="U" number="27" xmlns:help="http://openoffice.org/2000/help"/>Variable fields, regardless of type, can be made dynamic if they are dimensioned by ReDim at the procedure level in subroutines or functions). Normally, you can only set the range of an array once and you cannot <text:s text:c="" xmlns:text="http://openoffice.org/2000/text"/>modify it. Within a procedure, you can declare an array using the ReDim statement with numeric expressions to define the range of the field sizes.</p>
