This document introduces a new way to add scripting and OLE Automation capabilities to programs, such as applications or servers. With the advent of ActiveX™ Scripting, hosts can call upon disparate scripting engines from multiple sources and vendors to perform scripting between components. The script itself--language, syntax, persistent format, execution model, and so on--is left to the script vendor. Care has been taken to allow arbitrary language "back-ends" to be used by hosts relying on ActiveX Scripting to perform these tasks. The terms script and scripting are used throughout this document to mean an executable blob, whether that be a piece of text, a block of pcode, or even machine-specific execution byte codes.
