News for Application Developers If you are interested in using DEC C to build client/server appli- cations that interoperate with Windows[R] based systems, please see the release notes for important information on a new DIGITAL product called The Application Developer's Package for C/C++. Installation Information Installing DEC C for OpenVMS[TM] VAX[TM] requires the OpenVMS VAX operating system Version 5.5-2 or higher. The installation kit contains media for installing the DEC C compiler, as well as the DEC C/C++ Run-Time Components Version 6.0 for OpenVMS VAX Systems. Installing the full kit requires 34,000 blocks of free disk space for the compiler and up to 17,000 blocks for the DEC C/C++ Run-Time Components kit. To use DEC C on systems running OpenVMS VAX Version 5.5-2 or 6.0, you must install the DEC C/C++ Run-Time Components kit in a separate step before installing the compiler. OpenVMS VAX versions higher than 6.0 require that you install only the compiler.

License Registration Before you install and run DEC C Version 5.6 on a newly licensed node or cluster, you must first register a License Product Authorization Key (License PAK) using the License Management Facility (LMF). The License PAK may be shipped along with the kit if you ordered the license and media together; otherwise, it is shipped separately to a location based on your license order. If you are installing DEC C as an update on a node or cluster already licensed for this software, you have already completed the License PAK registration requirements. If you are installing prerequisite or optional software along with DEC C, review the PAK status and install the PAKs for any prerequisite or optional software before you install DEC C. Dependent Product Redistribution Information The DEC C/C++ Run-Time Components kit contains shareable image run-time components. When the DEC C kit is installed on OpenVMS VAX Version 5.5-2 systems, some of the shareable image run- time components replace older versions of existing OpenVMS components. DIGITAL has engineered the DEC C/C++ Run-Time Components kit specifically to allow redistribution with any application that uses one or more of these components. Redistributing this kit requires that the kit and its documentation be shipped to the remote site receiving any such application. See the DEC C/C++ Run-Time Components for OpenVMS VAX Reference and Installation Guide for detailed installation and redistribution instructions.
