[ferret_users] curv_to_rect_map function

[Luiz Paulo <lassad@xxxxxxxxxxx>]

Hi all,

I'm a new ferret user and I like to use curv_to_rect_map function on my 
data but when I tried to use it the program just fails to load the function 
with the following error message printed on my screen:


yes? let map = curv_to_rect_map (lonin,latin,lonlatout,10)
 **ERROR: command syntax: curv_to_rect_map (lonin,latin,lonlatout,10)
          unknown function "curv_to_rect_map"

Does anyone knows how can I load this function? or what am I doing wrong here?

Thanks for the help,

Luiz
