I'm afraid that I only have empirical evidence to offer: since we switched to using the API, all of our false positives have gone away and the applications have been stable for years.  %ADDR(PARM) and CEETSTA do not appear to be doing the same thing.

I've been searching for the source that I read on the mechanics of CEETSTA, but I haven't been able to re-locate it.  I will keep looking.

The gist that I derived from it was:

- Using %ADDR(PARM) is like peering out your windows to see who is coming up the walk.  You can get faked out.

- CEETSTA is the dog circling the neighborhood.  It knows where everyone is and what's in their pockets.

Understandably, until I can find the documentation that I was reading, this is reduced to an opinion.  The technique did help us and, hopefully, it can help someone else.

G'night.
