Hi again, Ha! Okay ... I'll take back the problem for a solution. Mind you, having finally solved the issue (I think! Please tell me if I'm wrong!), I ended up not feeling strongly about using a function anywhere. Richard, given that groups are defined in the groups.xml file, where is the flexibility needed for a function? Isn't the flexibility found in the groups.xml file? I've taken what I think is a very time-saving approach, first finding the groups that are in the area, and only then walking over the area alarms comparing each to the found groups. That way I'm not re-finding the found groups for every alarm, which I think is what the function was doing. I just can't figure out where function flexibility is needed ... I cannot see what needs to be tweaked that isn't simply in the groups.xml file. A transcript is below of what I hope is helpful this time around. Please let me know where I may have misunderstood the requirements, especially for flexibility. I hope the embedded comments are helpful. Apologies, again, for having jumped to the wrong solution in my earlier post. . . . . . . . . . . . Ken ~/t/ftemp $ cat groups.xml
