[SCM] 5 DL : 0: 在缓冲区marklist中存放了10名同学的分数成绩，将其转换为相应的等级成绩，存入缓冲区gradelist中。转换过程采用子程序实现。转换规则为： >=90：A >=80且<90：B >=60且<80：C <60：D 不用考虑边界情况，即假设输入的分数成绩都在0-100分中间。数据段定义如下： data segment marklist db 92,82,72,52,90,80,60,30,99,88 gradelist db 10 dup(?) data ends 子程序接口定义如下：子程序名：change 输入参数：AH，分数成绩输出参数：AL，等级 -在缓冲区marklist中存放了10名同学的分数成绩，将其转换为相应的等级成绩，存入缓冲区gradelist中。转换过程采用子程序实现。转换规则为： >=90：A >=80且<90：B >=60且<80：C <60：D 不用考虑边界情况，即假设输入的分数成绩都在0-100分中间。数据段定义如下： data segment marklist db 92,82,72,52,90,80,60,30,99,88 gradelist db 10 dup(?) data ends 子程序接口定义如下：子程序名：change 输入参数：AH，分数成绩输出参数：AL，等级
