Thought is useful to send a version of the code without the addin library.  Guess the point

is that to justify C# you ought to know what features C# offers that PHROGRAM does not.

It appears that " profile_GEOS.kpl " is faster than " contour_GEOS.kpl ".   So, unless

I learn more about C# or there are special functions more conveniently available within C#. 

I'll continue to prefer PHROGRAM.

Very cool, Jim. I have added your program to the downloads area for math and learning programs.

To use a term I heard a lot of during my days at Microsoft, you are the "thought leader" in our community on how to use Phrogram for weather-related programs. Are you with NOAA?

It's been a few months.  I notice that the NOAA site has added some GIF files that could be used as animation frames.

Decided to enhance the earlier work with the program movie_GEOS.klp using the files WVNH00.GIF, WVNH03.GIF,WVNH06.GIF

available on the NOAA site. "http://www.goes.noaa.gov/ " . The images can be found here http://www.goes.noaa.gov/WINDS/windsNHWVE.html
