Length field 0 corresponds to a move of 1 byte; Length field 255 corresponds to a move of 256 bytes. Hence, given N, an integer representing the length to be moved, it becomes necessary to subtract 1 from N before using that value in an EX in conjunction with MVC, CLC, etc. When N is initially zero, as in the case of an empty string, it becomes necessary to avoid the EX.
