FTP is the user interface to the ARPANET standard file transfer
  protocol.  FTP allows users to log into remote systems, transfer
  files to and from remote hosts, obtain listings of directories
  on remote hosts, and other common file operations.

  The FTP utility supports two styles of user interfaces, a
  DCL command interface and a ULTRIX command interface.  The DCL
  command interface is the default.  To select the ULTRIX command
  interface, define a symbol as follows:

        $ FTP :== $UCX$FTP/ULTRIX

  Most FTP commands require one or more file specifications.  Local
  file specifications must be valid VAX/VMS file specifications.
  Remote file specifications will be interpreted by the remote
  host and therefore must be valid to that host.  Any file specification
  which is not a valid VAX/VMS file specification must be quoted.
