Now that is curious. Why would C code be more efficient for code reuse than PL/X? Not to be overly tacky, but is IBM hoisting some BSD licensed code into various z/OS areas? I know that they did with OpenSSH. Much less expensive to port it than to create an SSH server / client from scratch. I wish, as usual, that IBM made their patches public. But I will guess that is why IBM likely will not use much GPL'ed software in z/OS. > > - Dave Rivers - -- 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.
