The story goes that the President Yeltsin and President Clinton were having an intense private discussion in the Kremlin. Suddenly a frantic figure bursts in. He identifies himself as the Minister of Finance. "President Yeltsin, I need your attention immediately. We have a big problem with the IMF. There is a need for immediate action." President Yeltsin waves his arm and says: "Code 6." Immediately the man calms down and walks out. A while later another frantic person breaks in. He identifies himself as the Foreign Minister. "President Yeltsin, we have a crisis with the Islamic nations. This will affect our southern areas. There is a need for an immediate discussion. This is urgent." President Yeltsin waves his arm and says: "Code 6." The man calms down and leaves. President Clinton is very impressed and asks what "Code 6" might be. Yeltsin tells him: "It simply means don"t take yourself so seriously." Sometimes in frantic situations there is a need for a quick and unambiguous signal that can defuse the situation. So code 6 is built around the above joke. There are things which are difficult to say directly because they are personal and may seem offensive. Having a neutral code gets over this difficulty. The code also covers more complexity than can be described in a word or two. The codes can also be used in alight-hearted way
