请编制程序，其功能是：内存中连续存放着20个ASCⅡ字符，如果是小写字母a～z之间的字符(包括字母a和z)，请把它们转换成相应的大写字母所对应的ASCⅡ字符；若为其他字符，不作转换。例如：内存中有：61H(’a’)，62H(’b’)，31H(’1’)，41H(’A’)，42H(’B’)… 结果为： 41H(’A’)，42H(’B’)，31H，41H，42H… 部分程序已经给出，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。请填空BEGIN和END之间已给出的源程序使其完整，空白处已用横线标出，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，或删去BEGIN和END之间原有的代码并自行编程来完成所要求的功能。对程序必须进行汇编，并与IO.OBJ连接产生可执行文件，最终运行程序产生结果。调试中若发现整个程序存在错误之处，请加以修改。【试题程序】 EXTRN LOAD:FAR,SAVE:FARN EQU 20STAC SEGMENT STACK DB 128 DUP ()STAC ENDSDATA SEGMENTSOURCE DB N DUP()RESULT DB N DUP(0)NAME0 DB ’INPUT1.DAT’,0NAME1 DB ’OUTPUT1.DAT’,0DATA ENDSCODE SEGMENT ASSUME CS:CODE,DS:DATA,SS:STACSTART PROC FAR PUSH DS XOR AX,AX PUSH AX MOV AX,DATA MOV DS,AX LEA DX,SOURCE ; 数据区起始地址 LEA SI,NAME0 ; 原始数据文件名 MOV CX,N ; 字节数 CALL LOAD ; 从"INPUT.DAT"中读取数据; BEGIN LEA SI, SOURCE LEA DI, RESULT MOV CX, NNEXT: MOV AL,[SI] CMP AL,’a’ JB (1) CMP AL, (2) J (3) UPPER2 SUB AL, (4) UPPER2: HOV [DI], (5) INC (6) INC (7) (8) NEXT; END LEA DX,RESULT ; 结果数据区首址 LEA SI,NAME1 ; 结果文件名 MOV CX,N ; 结果字节数 CALL SAVE ; 保存结果到文件 RETSTART ENDPCODE ENDS END START
