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

       /INPUT=input-filespec

    Optional. If you do not specify the /INPUT qualifier, FTP takes
    input from SYS$INPUT. If you specifiy this qualifier, you must
    also supply an input_filespec. FTP continues to prompt until it
    has a valid input_filespec.

    Runs a DCL command file with FTP commands.
