There's some irony to this thread. There's a frequent antipathy to z/OS UNIX (USS) expressed here. The spirit seems to be, "MVS (pre-OpenEdition, only) forever!" But considerable delight at the thought of applications moving from other hardware platforms to Linux on zSeries. That's supposed to be better? Perhaps the writers harbor a latent fantasy that when the z comes in to run Linux there'll be a spare LPAR or VM guest for good ol' z/OS. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
