The purpose is to confuse the heck out of the person who tries to understand
it. Using military vocabulary, so popular these these days, the "var" before
the declare block is here to confuse and deceive the enemy. You see, if the 
program was written in such a way that another human being could understand it 
and, god forbid, maintain it, the job security of the original coder would be 
in double jeopardy. With unemployment numbers as high as they are, coding clearly and 
documenting your code is a direct attack on the still frail economy.
Hopefully, my explanation answers your question.  Feel free to ask more questions.
