This would presumably split as ["logicalname","dir0",...,"dirk","name.ext"]
So for VAX/VMS you can't use file separators, but at least you can map to
a sequence of strings in a reasonably obvious way.  I'm quite happy for
versions to be ignored; it would probably be best to handle these by 
a special library for VAX/VMS.  MVS/MVT partitioned datasets are another
storY.  Perhaps there you could prefix the final component with a ":" if
a member name is meant.
