The same applies to z/OS, but even worse in that TSO is required to really do anything at least as far as "system maintenance" is required. I don't know about VSE, but in z/OS, even with TCP/IP, it is VTAM which is doing the actual I/O to the IP devices (well, at least with OSA devices). Who designed this? As an "amusement", I've been trying to see how much work I can do using z/OS's UNIX shell instead of TSO. The answer is: "Not really very much." As far as CICS is concerned, I can almost envision a TN3270 server "built in" to CICS. Or perhaps a BMS/IP where BMS supports IP terminals "directly" somehow. Of course, this will not be implemented by IBM without a business case. Is ICCF available via IP? Or is it even necessary? I'm not very VSE literate. -- 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.
