Hi Frank,

Yes, we have had that report. Barry has now completely rewritten the
Fortran bindings, replacing our old
binding generator, so that every exposed function should now have a
binding. This is a large change, but
should make everything much more maintainable. We plan to release 3.23 in a
week or two, and would advise
every Fortran user to upgrade, since this will be the standard going
forward. Does that timeline work for you?

  Thanks,

     Matt
