Please do everyone a favor and avoid re-starting this perpetual, fruitless debate. Seriously, OpenVMS and the better implementations of UNIX are all fine operating systems, each with its strengths and weaknesses. If you're in a position where you need to choose, select the one that best fits your own requirements, considering, for example, whether or not the layered products or specific OS features you want are available. Active development of new OpenVMS releases is underway, as well as the continuation of support. VMS6 removed, and replaced by Y2K section.
Various distributions are available.
The following CD-ROMs contain just the OpenVMS Alpha operating system. OpenVMS is written in a wide variety of languages. And this is certainly not a complete list. However, the rumor is not true that an attempt was made to write pieces of OpenVMS in every supported language so that the Run-Time Libraries could not be unbundled. Please see VMS16.
