The main reason seems to be HP-UX is System V and Sun is BSD. Now coming up is POSIX. I haven't seen the specs yet, but I get the impression that POSIX is more like System V. Can someone comment on this? In particular, what systems are currently closer to POSIX (i.e. which programmers are going to have to change more to be POSIX compatible)? I know HP is committed to standards (so is Sun; there are so many standards to choose from ;-), but does anyone know when HP, Sun, etc might reasonably be POSIX compliant? When that does happen, will some of these problems go away? Roger N. Clark bgphp1!rclark
