Is there a good example of how toupper() works?

   Or, for even less possibility for screw-ups:

	while ( '\0' != *duh ) {

The reason for the order becomes clearer in equality testing, when the
compiler will complain about ( '\0' = *duh ) and not ( *duh = 0 ). It is
real easy to catch a == vs. = problem this way.
