    Component Object Model (COM) is a technology from Microsoft that
    allows developers to create distributed network objects. Digital
    Equipment Corporation and Microsoft jointly developed the COM
    specification. The Compaq COM for OpenVMS kit included on the e-
    Business CD-ROM provides all the code and documentation you need
    to install Compaq COM for OpenVMS on your system and to develop
    COM applications.
