- tape operating system — (operating system) (TOS) An IBM operating system for System 360, used in the early days around 1965 to support the IBM 360 model 30 et al. TOS was a predecessor to IBM's Disk Operating System. TOS died out really early as disks such as the 2311 and 2314 became common with the IBM 360 whereas thet had been a real luxury on the IBM 7090.
- ulm's modula-2 system — (language) A Modula-2 compiler, library and tools by Andreas Borchert <[email protected]>. The compiler is derived from the ETHZ compiler for the Lilith system. Version 2.2.1 conforms to PIM3. It requires gas version 1.36 (to be found in the same directory). Commercial use requires a licence. It runs on Sun-3, Nixdorf Targon/31, Concurrent 3200 Series.
- virtual memory system — (operating system) (VMS) DEC's proprietary operating system originally produced for its VAX minicomputer. VMS V1 was released in August 1978. VMS was renamed "OpenVMS" around version 5.5. The first version of VMS on DEC Alpha was known as OpenVMS for AXP V1.0, and the correct way to refer to the operating system now is OpenVMS for VAX or OpenVMS for Alpha. The renaming also signified the fact that the X/Open consortium had certified OpenVMS as having a high support for POSIX standards. VMS is one of the most secure operating systems on the market (making it popular in financial institutions). It currently (October 1997) has the best clustering capability (both number and distance) and is very scalable with binaries portable from small desktop workstations up to huge mainframes. Many Unix fans generously concede that VMS would probably be the hacker's favourite commercial OS if Unix didn't exist; though true, this makes VMS fans furious.
- water-vascular system — a system of closed, fluid-filled tubes and ducts of echinoderms used in clinging, locomotion, feeding, and respiration.
