请编制程序ex9.ASM，其功能是：从20个有符号字节数据中取出负数并计算其绝对值之和(字型)，然后存放在指定的内存区中，多余的空间填0。
例如：
内存中有80H，02H，00H，7CH，7BH，11H，……
结果为80H，00H，FEH，00H，FDH，00H，85H，00H，……
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，运算的结果要求从RESULT开始存放，由过程SAVE保存到文件OUTPUT1.DAT中。补充BEGIN和END之间已给出的源程序使其完整(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。
对程序进行汇编，并与IO.OBJ链接产生执行文件，最终运行程序产生结果。调试中发现整个程序中存在错误之处，请加以修改。
