FlexCUB. But it only supports Escon, not Ficon. It emulates 3390 on SAN / PC type disk. I think part of the problem is with the support for legacy PDS and files with "hardware keys". Searching a PDS directory for a member is a very simple CCW chain. And is used a lot in IPL and NIP. So the first thing that would need to be done is to have IPL and NIP be able to support PDSE. Or, even better, something which has "members" but is superior to PDSE. I don't know why z/OS cannot use the CMS file system. It works, as you said, for z/VM. Or use whatever z/VSE uses for its libraries. I'm not z/VSE literate. And then there is the VTOC. It also has hardware keys. Now I'm curious how z/VSE supports FBA disks. Time to go look at some books. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
