     See: Fn 3700H (query switch character)

          Fn 3701H (set switch character)

 These two functions are ◄Undocumented► and ◄Obsolete►.

 They were intended as part of a system that would enable DOS users to
 select a character other than slash (/) as the lead character for command
 options.  See the obsolete SWITCHAR= CONFIG.SYS command.
