(1)编写分支结构.asm文件实现: 键盘输入以‘$’为结束符的长度不超过80的字符串（含字母、数字、其他字符），对其中的非数字字符计数。统计结果用十六进制数屏幕显示。

(2)编写分支结构.asm文件实现: 定义一串以‘$’结束的字符串，给每一个字符均加上偶校验位。统计有多少个字符因含有奇数个1而加上了校验位，结果存入N单元。

-(1) the preparation of branch structure. Asm file to achieve: keyboard input in　$ to end at the length of not more than 80 strings (including letters, numbers, other characters), of which non-numeric character count. Statistical results with a few hexadecimal display. (2) the preparation of branch structure. Asm file to achieve: the definition of a string with　$ end of string to each of the characters are combined with dual parity bit. Statistics because of the number of characters containing odd-numbered months 1 and added a parity bit, the result deposited in N units.
