Also on the PDF front, there was an excellent paper presented last month at SAS Global Forum, Getting the Right Report (Again): Your Compatibility Guide for ODS.pdf 9.2 by Scott Huntley and Bari Lawhorn of SAS.

And a general trick I picked up somewhere -- when searching the SAS Notes, try specifying the keyword "sascompat".

I realize that you are talking about in-language incompatibilities, but here are two "incompatibilities" that took us by surprise here at SAS Mecca:

1. PDF files created using the Output Delivery System (ODS) in SAS 9.2 end up being much larger than those created by the same code executed in SAS 9.1.3. This happens because SAS now embeds a number of fonts into PDF's. There are two SAS Notes about this phenomena and how you can address it:

SAS Support Usage Note 34277

SAS Support Usage Note 31474 (

2. The directory structure for SAS 9.2 TS2M2 (M2) changed from that of SAS 9.2 TS2M0 (M0) for Windows Client/Server installs. This necessitates a COMPLETE REINSTALL of SAS 9.2 in order to apply the M2 maintenance release to SAS 9.2:-( The same will be true for SAS Windows Client/Server sites that need to upgrade from M2 to M3 when it comes out in... say June. We decided to chuck the whole Windows Client/Server paradigm and go to local installs.

I will be interested in reading what other 'L-ers have to write in this thread!

Jim, best of luck in all of your SAS endeavors!

I hope that this suggestion proves helpful now, and in the future!
