In order for certain tasks to be completed in ArcView, Avenue scripts must be utilized. Scripts can be thought of as mini extensions. Extensions are plug-in modules that you can add to ArcView which allow it to perform certain tasks. Some examples of extensions include the Legend Tool, Image Analysis, and the Spatial Analyst. Scripts are similar to extensions in that they are addons, however, they do not perform the same advanced tasks. Scripts are created using ArcView's Avenue Scripting language. Scripts are usually created to speed up tasks that ArcView can do (without the need for extensions). The usual purpose of a script is to automate the task at hand.
