input-file

    Supplies one or more names of binary error log files to be used
    to produce an output dump file.

    name is SYS$ERRORLOG:ERRLOG.SYS. If you do not specify a device
    and directory, the system defaults to your current device and
    directory. If you do not specify a file name, the default file
    name is ERRLOG. If you do not specify a file type, the default
    file type is .SYS.
