Hi Bob,
I can see clearly that you know a lot about computers and you are right I do not know BCS. It is fun to know that you have been so involved with computer and glad you are enjoying your retirement. I hope to see the rapture before I retire. I only have a few more years to go! I have also worked as a sys admin on various versions of UNIX as well as other systems. I do understand X and what you are talking about. :) I have just started to use a MAC and that is why I found it humorous. I know that the MAC OSX is based on FreeBSD and is quite stable.
