VBScript Pocket Reference is a quick-reference guide to the VBScript language as of Version 5.5. It lists a concise description of all language elements by category for both VBScript itself and for the Microsoft Scripting Runtime (scrrun.dll), an additional object library that provides support for associative arrays and filesystem access.
