Command: ver
  VER displays the FreeDOS version information. By default,
  only the version of the command shell (FreeCOM) is reported.
Syntax:
  VER [/R] [/W] [/D] [/C]
  VER /?
Options:
  none  Shows COMMAND.COM version number.
  /R    Shows the KERNEL and COMMAND.COM version numbers. When
        VERSION=x.yy is set in CONFIG.SYS / FDCONFIG.SYS
        it also shows this DOS version number.
  /W    Shows the FreeDOS command shell warranty.
  /D    Shows the FreeDOS command shell distribution information.
  /C    The FreeCOM acknowledgements section. It lists contributors.
  /?    Shows the help.
Comments:
  The CALLVER DOS version is NOT shown by VER /R.
  VER is a command internal to command.com and needs no other file
  in order to work.
Examples:
  Example 1:
    ver     Shows COMMAND.COM version number.
    ver /R  Shows KERNEL and COMMAND.COM version number and
            if set, the DOS version number set by version.
    ver /W  Shows the FreeDOS command shell warranty.
    ver /D  Shows the FreeDOS command shell distribution information.
    ver /C  The FreeCOM acknowledgements section. It lists contributors.
  Example 2:
    In CONFIG.SYS / FDCONFIG.SYS:
      version=9.99 Sets DOS version number to 9.99
    In COMMAND LINE:
      ver /r       Shows KERNEL and COMMAND.COM version number and
                   DOS-Version 9.99
  Example 3:
    In COMMAND LINE:
      callver 6.67 Shows version number 6.67
      ver /r       Shows the version number 9.99 (see Example 2) or none.
