}I want to point out that this is a very ineficient way of doing
}things.  There's no need to remove and re-add the resource; you can
}just change it and call ChangedResource.  This would reduce the memory
}operations involved in removing and re-adding (which can be quite
}significant, leading the entire resource map to be resized in RAM) and
}reduce the size and complexity of your routine.  Your whole update
}routine would be just:
} 
}   aHdl = GetResource('DATA', 128);
}   /* At this point I init aHdl w/the data structure
}    * that I've maintained, in preparation for
}    * writing it back out.
}    */
}   ChangedResource(aHdl);
}   WriteResource(aHdl);	/* optional */

This looks good. My only statement is that my DATA will more than
likely change size between reading it and writing it. In which
case I would have to do a SetHandleSize, correct?
