No, I didn't miss that. I only stated it that way because I messed the math up the first time and I wanted to make sure I had it right this time. I knew you would correct me if I was wrong. I know it seems like an insurmountable number and it very well may be. I am not writing it off as effectively impossible without spending a little time setting up the self-pruning system I outlined above. I have done so in the past with seemingly impossible numbers (albeit not this large) with positive results. Unfortunately, I am more focused on real world problems (DB2 is a real PITA btw).
