!!! Overview
[{$pagename}] ([MVS]), was the most commonly used [Operating System] on the System/370 and System/390 [IBM] [mainframe] computers.
[{$pagename}] was developed by [IBM], but is unrelated to IBM's other [mainframe] [Operating System], e.g., [VSE], [VM], [TPF].
First released in [1974|Year 1974], [{$pagename}] was extended by program products with new names multiple times:
* first to MVS/SE (MVS/System Extensions),NB 1
* next to MVS/SP (MVS/System Product) Version 1,
* next to MVS/XA (MVS/eXtended Architecture),
* next to MVS/ESA (MVS/Enterprise Systems Architecture),
* then to OS/390 and
* finally to [z/OS|zOS] (when 64-bit support was added with the [zSeries] models).
[IBM] added [UNIX] support (originally called OpenEdition [MVS]) in [MVS]/SP V4.3 and has obtained [POSIX] and [UNIX]™ certifications at several different levels from [IEEE], X/Open and [The Open Group]. The MVS core remains fundamentally the same [Operating System].
By design, [Applications] written for [MVS] run on [z/OS|zOS] without modification.
