: I was only mentioning the data mishandling problems that can occur if one attempt to use retain to do re-ordering. Yes, of course, the side effects you mentioned exist and will continue to exist if SAS doesn't provide a way to simply modify the viewed/addressed_with_variable_list order (and, while it may not be called a pdv, variable lists can be used with all SAS procs).

However, SAS continues to choose not to, thus the kind of side effects you mentioned are also always there if one needs to modify/resturcture/add variables, etc. to their data.

As for procs and systems that are geared to only use point and click operations, and no code, I prefer to feed SAS data into R. I was extremely disappointed when SAS decided to not output or allow one to run EM with code. I'd really hate to see how much error has been introduced, but never noticed, because of that decision.

That's then may-be where metadata should come into play, be it as information maps or as a table metadata object and a library definition accessing data via metadata layer.

Arthur, for the first point we can agree assume. For the second points you could add now own code nodes with Eminer. You always can review the code and you can add R as node under some conditions.  I am mad enough to go for the support and implement those features and check their functionality.

The whole implementation is a technical nightmare to get well working. The statistical instability could be there, I had some distrust on some point not getting clear.

Your statistical distrust can be even greater looking what they are trying to do with SAS-VA. push some buttons and you get nice figures with predictions the intrepretation and evaluation of what is shown getting out of focus. That is another way of quick results but could winning a battle losing the war.  Ah we can agree on your second point too I see.
