X+ ** History:
X+ **       Feb 91    Written Tim Berners-Lee CERN/CN
X+ **       Apr 91    vms-vms access included using DECnet syntax
X+ **    26 Jun 92 (JFG) When running over DECnet, suppressed FTP.
X+ **            Fixed access bug for relative names on VMS.
X+ **       Nov 93    Derived from HTFile.c; Youki Kadobayashi WIDE
X+ **            deleted VMS code for simplicity.
