VMS Help CREATE, /TERMINAL, Qualifiers, /INPUT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /INPUT=filespec

    Specifies an alternate input file or device to use as SYS$INPUT
    for the new process. The default is to use the created terminal
    window for input. This qualifier can be used with or without the
    /DETACH qualifier.
