Three small commands which can manipulate a paht/file name.

BASENAME will extract the base filename from a path/filename, and optionally
remove a suffix.

TACKON will take a path and file name and append the filename to the path.

PATHNAME will take a path/filename and stip off the filename, returning the
pathname only.

The source, in Oberon-2 is included.
