Here's a quiz:
How would you write the following in C?

	VAR a, b, c : Char;
	...
	FOR c = a TO b DO ... END;

You can even assume that the body of the loop affects neither a nor b.
Hint:  the answer is *not*

	char a, b, c;
	...
	for (c = a; c <= b; ++c) { ... }

(just try a = 0 and b = 255 in the case of 8 bit chars).
