Base + Offset Addressing Mode - Stack Overflow

Web* The moffs8, moffs16, and moffs32 operands specify a simple offset relative to the segment base, where 8, 16, and 32 refer to the size of the data. The address-size attribute of the instruction determines the size of the offset, either 16 or 32 bits. ** In 32-bit mode, the assembler may insert the 16-bit operand-size prefix with this instruction.
