**-bo**\ [*ncols*][*type*][**w**][**+l**\|\ **b**]
    Select native binary output. Here, *ncols* is the actual number
    of data columns of type *type*, which must be one of **c**, **u**, **h**,
    **H**, **i**, **I** (capital i), **l** (lower case ell), **L**, **f**, and **d** (see **-bi**).
    For a mixed-type output record, append additional comma-separated
    combinations of *ncols* *type* (no space).
    Append **w** to any item to force byte-swapping or **+l**\|\ **b**
    for byte-swapping of the entire record. If *ncols* is not specified
    we assume that *type* applies to all columns and that *ncols* is
    implied by the default output of the program. **Note**: NetCDF file output is
    not supported.
