723	<h4>Restrictions</h4>
724
725	- perform only horizontal interpolations on scalar fields
726	- all masked and missing values are filled before interpolation
727	-> output data are not masked and have values everywhere.
728	- attributes (like valid_min...) are not updated
729	- see restrictions of <a href="..//Interpolation/fromreg.html">fromreg</a> and <a href="..//Interpolation/fromirr.html">fromirr</a>
730	- output mask is not used but, if the input file contains the mask
731	in a variable (defined by inmaskname), this variable will contain
732	the output mask in the ouput file
