An operand consisting of more than one byte is assembled in little endian order. The placeholders ro and wo are the number of bytes the instruction is expected to read or write, respectively. These counts are used for both memory and I/O access, but not for immediate operands. A negative value indicates that the operand byte order is big endian rather than the usual little endian. The placeholder rep is a boolean used to mark repeating instructions. The format string should refer to the {d} and {i} operands by name. Displacements are interpreted as signed integers, whereas immediate operands are always read as unsigned. The tables for instructions operating on the IX/IY index registers additionally use {r} in the format string as a placeholder for the register name. Relative jump instructions may specify {j} instead of {d} to output the displacement relative to the start of the instruction.
