	DOS and Windows have always internally accepted \ and /. The command line
	interpretor, however, only accepts \.
	
"The" command line interpreter?  There have been several ports of
UNIX-like shells to DOS.

	Also note that under windows filenames of the form:
	
	\\server\share\directory\file or //server/share/directory/file
	
	are also perfectly legal.
	
They were also legal in DOS.
