Well it's not much of a code as I have to keep changing it as I get older and, er, wiser and make evermore cockups. It's a far more movable feast than a code. Codes tend to become certain people's treasured babies, hard to wrestle away from them. The Catholic hierarchy, for example. People live longer, there are too many mouths to feed, more babies survive than ever before, we've had sexual liberation, we have epidemics of HIV, but the Church will simply not say that it's OK to use condoms, even though all sane people know that it is. That's codes for you. They can turn into unreasonable edicts wrapped in illogical and nonsensical and outmoded reasoning. Times change fast but codes are clung on to by the men of marble. I won't be writing mine down anytime soon.
