Do you know if > any documentation of the JrbCluster algorithm will be forthcoming?) Hi David, I've only just (since yesterday) gotten back to JAS. JrbCluster was debugged stand-alone; I haven't had a chance to try it in the JAS interactive environment, but that is where I'm headed. I should have documentation ready some time next week. (If my NT box hadn't gone casters up today, I might have said early next week.) Joanne
