1、2013年计算机等级考试三级PC技术上机（6）请编制程序，其功能是：将内存中存放着20个数字09之间的ASCII字符(包括数字0和9的ASCII字符)或SP字符(20H)，请将数字09之间的ASCII字符(包括数字0和9的ASCII字符)转换为相应的八位二进制数，并将SP字符转换为 $ 字符(24H)。将按上述方法处理后得到的20个字节存入内存中。例如：内存中有 20H(SP),30H(0),31H(1),31H(1),20H(SP),32H(2),39H(9)(共20个ASCII字符)结果为 24H($),00H,01H,01H,01H,24H($),02H(2),09H(9)(共20个字节
2、)部分程序已给出, 其中原始数据由过程LOAD从文件INPUT1.DAT中读入SOURCE开始的内存单元中。运算结果要求从RESULT开始存放,由过程SAVE保存到文件OUTPUT1.DAT中。填空BEGIN和END之间已给出的一段源程序使其完整(空白已用横线标出,每行空白一般只需一条指令, 但采用功能相当的多条指令亦可),或删除BEGIN和END之间原有的代码并自行编程来完成要求的功能。对程序必须进行汇编,并与IO.OBJ链接产生PROG1.EXE执行文件,最终运行程序产生结果(无结果或结果不正确者均不得分)。调试中若发现整个程序中存在错误之处, 请加以修改。试题程序：EXTRN LOAD:
