OpenVMS, often referred to as just VMS, [8] is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch ...
VSI BASIC for OpenVMS is the latest name for a dialect of the BASIC programming language created by Digital Equipment Corporation (DEC) and now owned by VMS Software Incorporated (VSI). It was originally developed as BASIC-PLUS in the 1970s for the RSTS-11 operating system on the PDP-11 minicomputer.

A VMScluster, originally known as a VAXcluster, is a computer cluster involving a group of computers running the OpenVMS operating system. Whereas tightly coupled multiprocessor systems run a single copy of the operating system, a VMScluster is loosely coupled: each machine runs its own copy of OpenVMS, but the disk storage, lock manager, and security domain are all cluster-wide, providing a ...
VAX MACRO is the computer assembly language implementing the VAX instruction set architecture for the OpenVMS operating system, originally released by Digital Equipment Corporation (DEC) in 1977. The syntax, directives, macro language, and lexical substitution operators of VAX MACRO formerly appeared in MACRO-11 , the assembler for the PDP-11 ...
"Files-11" is the general term for five separate file systems, known as on-disk structure (ODS) levels 1 through 5. ODS-1 is the flat file system used by the RSX-11 OS, supported by older VMS systems for RSX compatibility, but never used to support VMS itself; it has been largely superseded by ODS-2 and ODS-5.

In computer software, specifically the DCL command-line interface of the OpenVMS operating system, the DIRECTORY command (often abbreviated as DIR) is used to list the files inside a directory. [1] It is analogous to the DOS dir and Unix ls commands.
