Re: change in rcm2points_Wrap

Hi Alvaro,

The correct interface and call to rcm2points are:

undef ("rcm2points_Wrap")
function rcm2points_Wrap \
                       (yi[*][*]:numeric,xi[*][*]:numeric, fi:numeric \
                       ,yo[*]:numeric,xo[*]:numeric, Opt)

local fo, dimfi, nDim, pts
begin
   fo = rcm2points (yi,xi,fi, yo,xo, Opt) ; perform interpolation

====
It was *totally* wrong in 5.1.1

and, *partially* wrong in 5.2.0

Thank you VERY much

This will be changed.
