Marcus is correct in that DATAFILE does not specify the file that is
used for the reading of the data, but is used to tell the Makefile to
install that file to the datadir area when you do a "make install".

I think to get the effect you want, which is to specify a datafile
with a different name from the default <appName>.scm, you'll want to
use a custom LispArchiver instance, instructions on how to do that can
be found at in section 16.1.2 of the Swarm User Guide:

http://www.santafe.edu/projects/swarm/swarmdocs/userbook/swarm.user.user3.05.chapter.html#SWARM.USER.USER3.05-SIM-PARAMS-CUSTOM.SECT2

Basically you can create an instance of the archiver using the a
specified filename:

id archiver =  [LispArchiver create: globalZone setPath: "batch.scm"];

then you can do usual object creation, as per the other example:

if ((theTopLevelSwarm = 
      [archiver getWithZone: globalZone key: "batchSwarm"]) == nil) 
  raiseEvent(InvalidOperation, 
              "Can't find archiver file or appropriate key");

If you look in mousetrap, you'll find that MousetrapBatchSwarm.m has a
complete example (from which the user guide example is drawn from).
