Hi Raj, no .. not running away .... but need to thank atleast .. on my part. though i couldn't contribute . When Kyte & Lewis differ on their thoughts about this ..... i could do nothing but keep my head scratching ;) Really , it was an excellent thread for me to learn from. Where else can i see such experts sharing their views ?! Now i have got to know , how much COST means in a plan ... thought not clearly what COST really means. Regards, Prem.
