DOS Fn 3701H: Set Switchar
Compatibility: ◄Undoc► ◄Obs► 2.0-4.x
Expects: AX 3701H
DL desired DOS switch character
Info: This ◄Obsolete► function previously set a global "switch
character" and was even supported by the undocumented CONFIG.SYS
The idea was to provide a way to use a character other than slash
(/) as the lead-character in command-line switches (perhaps
freeing / for use in pathnames or allowing the UNIX-like dash (-)
as the switch character.
The concept never really caught on; most programs do not bother
to use Fn 3700H to check for changes.
Versions: 2.0-4.x This is an undocumented, though valid function.
5.0+ This function is ◄Obsolete► and no longer supported
by DOS. It does not return an error, but is ignored.
