I don't know how many people is still using vi nowadays. But I still am. But today, I just found out the 'vi' on AIX 3.1 doesn't know the -x option at all. I found -x option on all other UNIX machine I've used here, SUN, Ridge, Sequent.... Is there anyone knows why the -x option is lost by IBM? --- Guangliang He ghe at physics.orst.edu
