Bin Laden's Code Message

Hearing on going rumors from the American President Bush, Bin Laden had enough of it. He decided to end this rumor and let Bush know he was well alive. Laden sent a letter with a message to Bush. But when the President opened the letter, all he found was a code:

370HSSV 0773H

The President was confused and couldn't understand the code. He decided to crack the code by sending it to the FBI, CIA, and NSA. Nobody could find out what in meant! Later sometime in England the MI-6 called the President and to told him: " Sir, you were reading the code upside-down."
