Re: Fortran Functions Used by Ferret

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Jeremy,

There is support for external functions in V4.91 but it is still at the
beta level:  still under development.  You can learn more about them by
checking the Ferret home page and looking at the section on External
Functions:

http://ferret.wrc.noaa.gov/Ferret/External_Functions/

This should be enough to get you started but you should be aware that the
next release of Ferret (V5.0) will be out in the not-too-distant future and
the external functions API is bound to change slightly.  If you don't mind
making minor modifications to you external function code when you switch to
the new release, I see no reason why you shouldn't start using the external
function capabilities of Ferret today.

Let me know if you have any problems or questions.
