The APPEND/APPLICATION_PROTOCOL=FTAM command accesses the FTAM
    appending utility, which appends files between FTAM systems within
    an OSI network. The appending utility operates on a combination of
    local and remote FTAM or on remote files only. Using this command,
    you can:

    o  Append an input file to a single output file

    o  Concatenate two or more input files into a single output file

    If only local files are specified, the APPEND/APPLICATION_
    PROTOCOL=FTAM utility passes the command to the RMS appending
    utility. In that case, all command qualifiers operate in the
    standard manner documented in OpenVMS help.
