In fact, many programmer purposely include the Option Explicit statement in all of their VBScript programs which mandates that all variables be explicitly declared.   Code: <% Dim myvariable %> <% Dim OneVar, TwoVar, ThreeVar, FourVar, MoreVar, EvenMoreVar %>   Dim can also be used to create static (fixed) and dynamic arrays.   A static array has the number of elements declared by the Dim statement. However, you must remember that the elements in an array are numbered starting at zero. Consider the following Dim declaration. It creates a static array containing six elements that are numbered 0, 1, 2, 3, 4 and 5.   Code: <% Dim SixElementArray(5) %>   A dynamic array is declared using empty parentheses. At a later point in your program, you can use the ReDim statement to declare the number of dimensions and elements. In fact, you can redeclare a dynamic array as many times as you desire.   Code: <% Dim SomeArray() ... ReDim SomeArray(22) ... ReDim SomeArray(500) %>   Arrays can also have up to sixty dimensions. For example, the following code creates a three dimensional array. The first dimension has 23 elements, the second dimension has 15 elements and the third dimension has 201 elements. Therefore, there are a total of 23x15x201 = 69345 elements in this array.   The number of dimensions that you can create is limited by the available memory. If you exceed the available memory while declaring an array, you will get an error message.   Code: <% Dim ThreeDimensionArray(22, 14, 200) %> Copyright 1999-2001 by Infinite Software Solutions, Inc.
