input-file

    Supplies one or more names of binary error log files to be
    converted to the older format.

    If you do not specify an input file name, the default input 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.
