VBScript is a subset of Visual Basic used in Active Server Pages and in Windows Scripting Host as a general-purpose scripting language. VBScript is often used as a replacement for DOS batch files.

VBScript is interpreted by a script engine, either ASP in a web environment, wscript.exe in a Windows environment, and cscript.exe in a command-line environment.

VBscript files typically have the file extension .vbs.

Example program (to put into a file 'hello.vbs'):

msgbox "Hello world"

If the Windows Scripting Host is installed correctly and activated the program will run when the icon is double-clicked.
