Respected Monks,

Thank you for your direction and guidance.

Anonymous Monk, my intention of using $wwn and @wwn is not to confuse.I do understand that @wwn and $wwn are two seperate entities and that having the same name doesn't mean that they are related in any ways, unless ofcourse I say $wwn[0] or something like that which indicates that its a scalar context of @wwn. I used $wwn and @wwn because the name WWN stands for World Wide Name and this ways, I can make a mental note that both these refer to it, though inherently they are not related.

ww, I will surely follow indentation.
