<P>
For geographical data, the first column is expected to contain longitudes
and the second to contain latitudes.  To reverse this expectation you must
apply the <B>-:</B> option.  Optionally, append <B>i</B> or <B>o</B> to restrict
the effect to input or output only.  Note that command line arguments that may take
geographic coordinates (e.g., <B>-R</B>) <I>always</I> expect longitude before
latitude. Also, geographical grids are expected to have the longitude as
first (minor) dimension.
