VMS Help TCPIP Services, FTP, Command Procedures, Initialization Command Files  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Initialization command files can customize your FTP sessions
    with SET, ENABLE, and DISABLE commands. These command files
    are optional. They eliminate the need to enter individual FTP
    commands, and run automatically when you invoke FTP.

    Initialization command files:

    o  Contain only VMS commands

    o  Contain only one command per line

    o  Generally named SYS$LOGIN:FTPINIT.INI
