external functions Ferret for windows

[viviane menezes <viviane@xxxxxxxxxxx>]

I have been using Ferret for a long time. Now, I installed Ferret v.5.22
for windows but I have one double: Can I use external functions, for
example SCAT2GRIDGAUSS_XY , in version for win? If, it's possible, how
do I do?

Thanks,

Viviane
