No, Paul, the maximal length value that can be specified in a DS instruction for character (C) or hexadecimal (x) values is 65534.
Your maximum does, however, apply to DC assembler instructions. It may also be worth noting that trying to catch John [Ehrman] out on a detail like this one is usually a mug's game. Like all of us, he can be guilty of a fat-finger typo; but I have never known him to be substantively wrong about a quantity. John Gilmore, Ashland, MA 01721 - USA
