In <10311@hoptoad.uucp>, tim@hoptoad.uucp (Tim Maroney) says that
(Str255 *) is a "nonsense" type. Perhaps this is true. I'm ready
to give up trying to find a better answer.

But before I do so, here's a final twist on the example. First,
the appropriate variable declarations:

	Str255
	    temps, *tempp;
	unsigned char
	    ch;
	int
	    i;

Now the two example expressions:

	ch = temps[i];
	ch = (*tempp)[i];

Both of these generate virtually identical code. The only difference,
apart from the reference to different variables, is that in the first
expression, the index is treated as a word, while in the second expression,
the index is a longword.
