Does the dragon go through the closed > door? Unfortunately in this mail, the dragon does go through the door. Had I payed closer attention to what I was saying when replying, it wouldn't. How ghastly of me to write that (and worse, I have it all written up correctly in my D-doc...shame on me). Not everything can be broken up like that, the general case of a one-step process concurrent with a two-step process, both with a common object like the door being a fine example. I confuzzed the thinking about loops over multiple objects with the 1:2 step process case...
