BREAK_PATH()

     Breaks up a path string into its component directories.

     Result = BREAK_PATH( PATHS [ /NoCurrent])

     PATHS   = A string containing one or more directory paths.  The
               individual paths are separated by commas, although in UNIX,
               colons can also be used.  In other words, PATHS has the same
               format as !PATH, except that commas can be used as a separator
               regardless of operating system.
               A leading $ can be used in any path to signal that what follows
               is an environmental variable, but the $ is not necessary.  (In
               VMS the $ can either be part of the path, or can signal logical
               names for compatibility with Unix.)  Environmental variables
               can themselves contain multiple paths.

      The result of the function is a string array of directories.
      Unless the NOCURRENT keyword is set, the first element of the array is
      always the null string, representing the current directory.  All the
      other directories will end in the correct separator character for the
      current operating system.

      /NOCURRENT = If set, then the current directory (represented by
               the null string) will not automatically be prepended to the
               output.

      None.
