Your method works fine IF you only need sequential access to the file AND you can make a copy and work with the copy. Not always the case. The only way around that problem is to do what Alan suggested; write a replacement library that can use the hooks provided and work with either the CMS filesystem, or the new VSE/VSAM interface either directly or via the VSE connectors (probably the best option). It'd be a great IBM product -- we could call it... Hmm, maybe CMS VSAM? On the other hand, since IBM has said they aren't going to release any of the modern language compilers for CMS other than C/C++ (which they need to maintain CP these days), I think that says a lot about the future for CMS application development and the fate of any commercial product that would attempt the development of such a VSAM replacement. At least we're finally free of AMSERV. 8-) -- db
