ADD A, 5
现在,A和5两者都是直接的。 是否允许使用大会语言?
这是否在电话中? A?
通常为<代码>A。If, 允许。 查阅A的定义(例如,带有该标签的DD pseudo指示)
如果是海数(通常写成0Ah,%0x0a)当然可以工作
如果A真的即刻(如或类似的>)在x86中不允许。 通常不允许有直接目标歌剧的指示,因为结果会被抛弃。
More likely you are making a wrong assumption "Now A and 5 both are immediate" in your question and sehe s explanation is right.
