Operands

The existence and meaning of the operands depends on the mnemonic used.

The existence and meaning of the operands depends on the mnemonic used. Some mnemonics do not require any operands. Other mnemonics require one or more operands.

The assembler interprets each operand in context with the operand's mnemonic. Many operands are expressions that refer to registers or symbols. For instruction statements, operands can be immediate data directly assembled into the instruction.
