I'm a little confused about the type of th argument to the function P.
In the first two calls to P we're passing in a string literal, but in 
subsequent calls we've got a mixed type expression; e.g.

	P("| " + (*u/4)%2)

Here the argument seems to be the sum of a string literal and an integer. 
What's happening here? Is th first character of the string literal being 
cast to an integer before the addition occurs?
