Command: ? (question mark)

  With '!' and '?' CONFIG.SYS / FDCONFIG.SYS can be made interactive.
  CONFIG.SYS lines that begin with '?' will be queried:
  The user will be asked for confirmation before a CONFIG.SYS
  line that begins with '?' is run.
  CONFIG.SYS lines that begin with "!" will be processed
  even when single stepping, see: F8.
  '?' is a CONFIG.SYS / FDCONFIG.SYS command.

Syntax:

  ?  other config.sys command such as DEVICE?=...

Options:

  - none -

Comments:

  '?' - ALWAYS ask if a single line shall be executed.
  '?' has nothing to do with 'command /?' (show the help).
  '?' is a command internal to kernel.sys and needs no other file
  in order to work.

Examples:

  Example 1:

    COUNTRY?=049,858,C:\FREEDOS\BIN\country.sys (german setting)
    LASTDRIVE?=Z
    FILES?=20

    BUFFERS?=30
    DEVICE?=MyNetWorkDriver.sys
