WebbThe OFFSET operator returns the offset of a data label. The offset represents the distance, in bytes, of the label from the beginning of the data segment. In Protected mode, an offset is always 32 bits long. In Real-address mode, offsets are only 16 bits. WebbThis directive simply tells the Assembler that there are no more instructions or directives to be assembled.
