How does GrADS work internally when drawing?

Hi Jennifer,

that's lots of ideas, thanks!

I had something like this in mind:

--
function snowflake()
if (csnowsfc = 1)
  ret="*"
else
  ret=""
end if

return ret

...

set gxout grid
d snowflake()
--

This would - of course - require that GrADS is going through the grid
and provides the location to the function.
But it would be pretty handy if this concept would work, right? :)
