pathname separator

   <file system> The character used to separate elements of a
   {path} or {pathname}.  Under {Unix} and {POSIX.1} compliant
   systems the pathname separator is the (forward) {slash}, in
   {MS-DOS} {backslash} serves the same purpose.  For obvious
   reasons the no directory or file name can contain this
   character.
