hello. COMPAT_IBCS2 implements the functionality necessary to run SCO OS/5 binary files. I haven't used this in a long while, but it was good enough to run a whole set of Oracle tools better than they ran under the native OS. (I used it with great success under NetBSD-1.4). I realize that's a long time ago, but SCO hasn't changed their binary format for this platform in forever and there used to be a lot of closed source software that ran under that platform. SCO was pretty much pure SVR3, so noting that COMPAT_IBCS2 implements SVR3 functionality is pretty much correct. Is anyone still using it?
