Several people mentioned that SYSVR3 does not have sockets and I agree. I was thinking about the socket packages that are provided by 3rd party vendors. I am curious if they integrate sockets into the file system or write them as a device driver. If any of this is public domain I am interested in acquiring the code. However, SYSVR4 does have sockets based on streams and I am curious how it maintains sockets for dup and fork operations. Dreez
