In any case, too many things would need to be enhanced, starting with IPL and NIP processing. Then all users of BPAM would need to be PDSE compatable because an old style PDS cannot reside on FBA. Or z/OS would need to implement an ECKD on FBA emulation within itself. Oh, and keyed BDAM files, if any such monsters still exist, could not be "natively" supported on FBA. Anything that required hardware keys cannot be "natively" supported on FBA because FBA doesn't have that concept. There may be some code out that using EXCP or XDAP which requires hardware keys. Why should IBM do this? It won't make them any money that I can see. It might even end up costing them money if the FBA versions of the 2107 cost less than the ECKD versions. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
