That is only scratching the surface of the overall power of this cool scripting language. It looks like it originally started out as an automation tool to automagically click dialog boxes for you in a scripted way. One of the example scripts
installs WinZip without any user interaction.
Version 3 has morphed into a more BASIC-ish language. One of the best aspects is that you can easily make GUI dialog boxes and neat automation tricks that are hard or impossible to implement in native VBScript.
You can also compile your scripts into self contained EXE files which is perfect for login scripts and/or application deployment scripts.
You can read more about it and download the application
