这个时钟程序是我在1993年编的一个小程序，现在贴出来给大家做参考，它执行后驻留内存，到整点时会报时，你可以用 Ctrl-Alt-U 把它从内存中下掉，可以用 Ctrl-Alt-C 变换颜色，用 Ctrl-Alt-O 把报时声音关掉（如果感到讨厌的话），在驻留内存时，用了直接改内存控制块的方法，所以用 MEM 或 MI 无法在内存中看到它，键盘控制用了直接截取 INT 9 的方法。 这个程序虽然很小，编译后才1K多一点点字节，但是麻雀虽小，五脏俱全，在这个程序中，你可以参考到以下编程方法：如何驻留内存；如何截取中断向量；如何在硬件层次上应答键盘；如何截取组合键。 要编译、连接成*.com文件-this is my clock procedures in 1993 a series of small programs, is now posted out to you for reference. following the implementation of its presence memory, the whole point of the talks will be, you can use Ctrl-Alt-U from its memory under the swap. can use Ctrl-Alt-C transform color, using Ctrl-Alt-O put timekeeping voice switch off (if the annoyance), in the presence of memory, using a direct change memory control block in the way that they use MEM or MI in the memory not see it, keyboard control using a direct interception of the INT 9. This procedure Despite its small size, after compiling a little more than 1K byte, but Sparrow small, perfectly formed, in the process, you can refer to the following program : how the presence of memory; how interception interrupt vector; in response le 下载
