operation code
     
         or "op code" the part or parts of a machine
        language instruction which determines what kind of action the
        computer should take, e.g. add, jump, load, store.  in any
        particular instruction set certain fixed bit positions
        within the instruction word contain the op code, others give
        parameters such as the addresses or registers involved.
        for example, in a 32-bit instruction the most significant
        eight bits might be the op code giving 256 possible
        operations.
     
        for some instruction sets, certain values in the fixed bit
        positions may select a group of operations and the exact
        operation may depend on other bits within instruction word or
        subsequent words.
     
        when programming in assembly language, the op code is
        represented by a readable name called an instruction
        mnemonic.
