VER
[/?]
[/R]
/?/RThe VER command displays the version numbers for both the operating system and the command interpreter. The three numbers are, respectively, the major version number, the minor version number, and the revision number.
Note: Some operating systems return a version number from the "query version number" system call that does not match the version number printed on the side of their boxes. Other command interpreters attempt to translate such version numbers into the "human readable" version number. This command interpreter does not. The version number displayed is exactly what the operating system has returned from the system call.
