I want to table this discussion until I have the opportunity to code and implement software that will prove what it is that I am trying justify. I have just arrived home from the USA and Sunday I leave for another weeks' conference. Once I return from that conference I will have the opportunity to prove my case. I want to thank everyone for their contributions on this topic and I hope that you will bear with me and we can resume after I know something definite. Thanks again, Hosnieh
