Re: RPGIV: Subfile "sort" thoughts

When very large files meet interactive needs, I don't see how you can avoid
creating a permanent access path for each necessary view.   If the system
you are working on is powerful enough to dynamically create the SQL views
without adversely impacting system peformance, it will even more easily
accomodate the seven permanent access paths.  -Dave K.
