Nettet20. feb. 2024 · mov [BX],10H 将10H送给按BX内容间接寻址的一个存储空间,但是[BX]无法推断出该空间的类型(字节/字/双字? ),后面的10H是个常数,显然也没有类型, … Because on x86 systems the low byte of some data is stored in the first byte and the high byte is stored in the second byte, the value 1234h would be stored as two bytes:34h in the first byte and 12h in the second one. The same is true for 78Bh: 8Bh is stored in the first byte and 07h is stored in the second one. EDIT
