80x86、80x87结构与汇编语言程序设计

资源集合。关于80x86、80x87结构与汇编语言程序设计的2.在AH中放功能号,然后引用中断2H指令这是向该者推荐的方法本章中的所有例子都采用这个方法3.对于与CPAM兼容的那些功能调用(O4I),可以用以下方法来调用:(1)传送所要求的参数至适当的奇存器:(2)把功能调用号传送至CL寄存器;(3)在当前码段执行一个段内调用到单元5在用这种方法实现调用时,并不要在AL中传送参数。而且在这种调用时,AX中的内容总是被破坏的暴统调用的宏指令NAMEB: MACRO, LIBREAD KLD AND ECHOMACROMOVAl.T21HENTISPAY CHARMACROCHARACTERMOVDL ChaRaCTERMOVAH, 2不NDMAUX INPUTMACROMOVAH, 321HENDMAUK.改TPTMACR们MOWAH, 4ENDMPRINT- CHARMACROCHARACTERDL CHARACTERAH+ 521HENDMd]R CONSOLE, IOMACROSWITOMOIVMCYAH, 621HENDMDIR.
