Thanks for the code example. Since most of my structures are dynamic and are altered during the iteration of the schedule, the safety of the collection will usually matter. So, I typically prefer to schedule individual Steppables. I use the composite Steppables sparingly. Thanks to you and the rest of the Mason crowd for your efforts. I appreciate them. -- glen e. p. ropella =><= Hail Eris! H: 503-630-4505 http://ropella.net/~gepr M: 503-971-3846 http://tempusdictum.com
