this is a very interesting topic and i would like you guys , when time permits , to expand on this and post more of your findings, i have read and have a basic understanding of the technical jargin, but i find i learn more from the real world examples the community exibit in these threads, especially interested in the explinations posted by willyb and bhorde as they have a unique ability to express in laymans terms what is difficult to grasp from the technical manuels available.... thanks guys...

 

:O)

Y'all have a great day.
