汇编语言编写的类似俄罗斯方块的游戏程序-compiled languages like Tetris game procedures

汇编语言实现两台微机之间通过RS-232C电缆连接实现串行通信。 1、异步方式全双工通信，每次传送单个字符，能连续发送和接收。 2、通信双方采用程序查询方式。 -Microcomputer assembly language to achieve between the two RS-232C serial communication cable connection. 1, full-duplex asynchronous communications, each transmission of a single character can send and receive continuous. 2, communications procedures for both the use of inquiry methods.

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
