通用数据传送指令. MOV 传送字或字节. MOVSX 先符号扩展,再传送. MOVZX 先零扩展,再传送. PUSH 把字压入堆栈. POP 把字弹出堆栈. PUSHA 把AX,CX,DX,BX,SP,BP,SI,DI依次压入堆栈. POPA 把DI,SI,BP,SP,BX,DX,CX,AX依次弹出堆栈. PUSHAD 把EAX,ECX,EDX,EBX,ESP,EBP,ESI,EDI依次压入堆栈. POPAD 把EDI,ESI,EBP,ESP,EBX,EDX,ECX,EAX依次弹出堆栈. BSWAP 交换32位寄存器里字节的顺序 XCHG 交换字或字节.( 至少有一个操作数为寄存器,段寄存器不可作为操作数) CMPXCHG 比较并交换操作数.( 第二个操作数必须为累加器AL/AX/EAX ) XADD 先交换再累加.( 结果在第一个操作数里 ) XLAT 字节查表转换. ── BX 指向一张 256 字节的表的起点, AL 为表的索引值 (0-255,即 0-FFH) 返回 AL 为查表结果. ( [BX+AL]->AL )

This book uses the Python language to teach pro - gramming concepts and problem -solving skills, without assuming any previous program- ming experience. With easy-to-understand examples, pseudocode, flowcharts, and other tools, the student learns how to design the logic of programs and then implement those programs using Python. This book is ideal for an introductory programming course or a programming logic and design course using Python as the language. As with all the boolts in the Starting Out With series, the hallmark of this text is its clear, friendly, and easy -to-understand writing. In addition, it is rich in example programs that are concise and practical. The programs in this book include short examples that highlight specific programming topics, as well as more involved examples that focus on problem solving. Each chapter provides one or more case studies that provide step -by-step analysis of a specific problem and shows the student how to solve it.
