[Jennifer Adams]

Yes, it will be something like defval, but more general, and it will handle expressions instead of single grid point values. The user interface is still under development. --Jennifer

The general idea is that you carve out a space in memory, and populate it with data or with results of operations on data, and those operations can be done by built-in or external functions. It won't be exactly like UDFs were in the old days, it'll be more much more flexible.
