No, I use what I mean. Are you trying to imply that the three
things you mention have the same value? (I grant that on some
machines with some compilers they might. I'm sure on other machines

Multi-character constants are "implemntation defined" (K&R2 page 193)
thus are for portable code UNDEFINED.
