/*
Name: Seth Hopper				Date: 12/15/00  			Box # 918

This is blackjack, it works fine except there is some problem getting the cards.  I get the same ones everytime and that should not be.  I've looked for the problemfor many moons now and I have no clue, I am very frustrated and I am very tired, this is what you get.  Sorry.
