两个经典程序：显示系统时间，转换（大小写字母转换、二进制/八进制/十进制/十六进制间转换）...

显示当前系统时间-show the current time system

这个东东是我刚写出来的,这可以完成定时1秒的功能,并且使用定时器来完成,定时精度高,可靠性高.-I just write out, it can be a regular seconds to complete the function, and the use of timers to complete, regular high accuracy and high reliability.

从键盘读入一个四位的十六进制数，CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制，所以每读入一个十六进制位后，即可将其对应的4个二进制位依次输出。由于数字‘０’~ ‘９’的ASCⅡ码为30H～39H,字母‘a’～‘f’与 ‘A’～‘F’的ASCⅡ码为61H～66H 与41H～46H ，因此，如果输入的字母为数字‘０’～‘９’，则其低４位即为对应的二进制位；如果输入的字符为字母‘ａ’～‘ｆ’或‘Ａ’～‘Ｆ’，则需要减７，然后通过移位将低４位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number
