Sure, I could do that, but would it answer the question I asked?

The doc mentions DPA < 2G, DPA and external page space, but I don't see any formula for calculating the SYSLIM that would be the default if none were specified in the SYSTEM CONFIG. The current config file limits were determined in a galaxy far, far away at a time long, long ago. I was wondering how they would compare to the current system defaults which may well be more generous than the limits that have been set. The problem is, we are as close to 24X365.25 as we can be, so it may be a long time before I can bring the system up without the config limits to see.
