/sys$common/syshlp/helplib.hlb COPY, /RCP, Qualifiers, /USERNAME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /USERNAME=username

    Optional qualifier that specifies the remote user name. The
    standard operation is to log in to a remote system using the same
    user name as at the local terminal. The command supports quoted
    parameters in the /USERNAME value.
