Thanks for helping me work through this... There needs to be a new redbook, titled: "The little things that you forget along the way".
Thanks again, Offer. David Diep What would you like to see in the renovated Martin Luther King Jr. Memorial Library?

The home statment order only matters with vipa addresses... The way it works is all addresses after the vipa are sourced by it if the sourcevipa parameter is specified... If you want somthing to be excluded from that vipa you must place it before the vipa statment... It is all in the books :-) A few years back it was strange for me to read it as well...
