By the way: I have no doubt that IBM will eventually make the SFS available for large systems. However, it is not clear to me that this will happen with CMS6. Maybe we'll have to wait until CMS7 to get SFS on *BOTH* large (be it XA or HPO) and small systems. And maybe this CMS7 will be quite different from CMS6. Clearly, I don't want to have to do this (probably) huge amount of work twice, so if CMS6 is not "the" SFS version, I'll wait until CMS7. Eric
