How is a FILTLIST substantially different/harder to maintain than a " list of dataset names and patterns"?
I don't remember DVC being part of &MAXSIZE when I did this. I also found that setting DVC to a more reasonable number like 4 or 8 works just as well as 59 without the serious impacts 59 can have elsewhere.
