Robert, I believe the SAS comment is referring to extended format data sets which is an older form of sequential data sets which also supported >64K tracks, but which was incompatible with EXCP, as SAS has mentioned. The new support does require some changes to EXCP programs, but they can support >64K tracks now.

As a result, SAS data libraries in that format are not supported. This is not a SAS issue. IBM has made a deliberate design and decision not to provide EXCP support for extended sequential data sets on disk. Since SAS uses EXCP to process direct access bound libraries, the direct access bound libraries may not reside in extended format sequential data sets. Consequently, a direct access bound library may occupy at most 64K tracks on any given volume. </quote> So the maximum for SAS libraries would be around 210 GB? Anybody ever encountered a SAS library similarly large? (Mine max out at some 15GB).
