Which gives the following relative ordering between SV and POSIX.1: SVr1 SVr2 SVr3 POSIX.1-1988 SVr4 POSIX.1-1990 SVID 4 And the following relative ordering between BSD and POSIX.1: 3BSD 4BSD 4.1BSD 4.2BSD 4.3BSD POSIX.1-1988 POSIX.1-1990 4.4BSD Because many of the system calls I updated listed SVr4, and some listed 4.4BSD, I want to check that it makes sense to list them after POSIX.1-1988. In case, for example, SVr4 is known to have influenced POSIX.1-1988 prior to being officially released. (I've also taken your recommendation and am trying out mutt(1), starting with this email. It's certainly a learning curve, but I'm slowly getting there!) -- Take care, Seth McDonald.
