Yep. You caught them. Of course, the release notes do note the shared memory differences from SVID (Xenix uses "far" pointers - "far" is a Microsoft C dependent keyword). They also note on difference in ptrace (it doesn't fail in one case where it's supposed to) and a few differences in the termio implementation (QUIT, ERASE and KILL are different, etc.). > [ csh is braindamaged, he says, because it doesn't work the same as the csh he uses ] OK. >This isn't a flame on Xenix or Microport.

It's amazing we can do anything useful at all with such terribly brain damaged hardware and software but, still, we perservere. Xenix, BSD, real SV, SIII, UTS, HP/UX, V7, etc., are all slightly different. Everything has bugs. Brain damage is where you find it. Memory models and virtual memory, as noted, have little to do with Xenix. What difference does it make, really. -- Greg Laskin "When everybody's talking and nobody's listening, how can we decide?"
