VER
Main article:
ver (command
An internal DOS command, that reports the DOS version presently running, and since MS-DOS 5, whether DOS is loaded high. The corresponding command to report the Windows version is winver. Values returned:
- MS-DOS up to 6.22, typically derive the DOS version from the DOS kernel. This may be different from the string it prints when it starts.
- PC DOS typically derive the version from an internal string in command.com (so PC DOS 6.1 command.com reports the version as 6.10, although the kernel version is 6.00.)
- DR-DOS reports whatever value the environment variable OSVER reports.
- OS/2 command.com reports an internal string, with the OS/2 version. The underlying kernel here is 5.00, but modified to report x0.xx (where x.xx is the OS/2 version).
- Windows 9x command.com report a string from inside command.com. The build version (e.g. 2222), is also derived from there.
- Windows NT command.com reports either the 32-bit processor string (4nt, cmd), or under some loads, MS-DOS 5.00.500, (for all builds). The underlying kernel reports 5.00 or 5.50 depending on the interrupt. MS-DOS 5.00 commands run unmodified on NT.
- The Winver command usually displays a Windows dialog showing the version, with some information derived from the shell. In windows before Windows for workgroups 3.11, running winver from DOS reported an embedded string in winver.exe.
