Great!  I followed the example to begin with, so that was my starting
point.

Thank you.  I saw the way that DEP works within the macro, and I rewrote
it a few times in an attempt to pass around the foreign array directly
and use grid:gref inside my dynamics function.  I guess I just need to
try a few more different things (like I said, newbie here).

I joined when I got the `your message needs to be approved' mail; sorry.
