There are different ways this can be done.  It is one of the most 
frustrating things about learning swarm, I think, because there is such 
a great variety of ways to do it.

The way described in the User Guide still works!  I'd suggest that as a 
first step.  Then there is the newer way using FCall thingies. If you 
read the Heatbugs source, you should see a CPP flag for FAST which 
causes that thing to work. There is a working java example here prepared 
by Marcus Daniels:

The idea is that you wrap the message and arguments together in an 
object, then pass that to the schedule when needed.

As I understand it, the problem with the old way is that it runs slower 
because objects are not typed.
