汇编语言实验报告三

班级：20144：：15X16ASCII10H100H的所有字符，即以行为主的顺序及ASCII码递增的次序依次显示对应的字符。每16个字符为一行，每行中的相邻两个字符之间用空白符(ASCII为0)隔开。windows10DosBox，masm[表格形式显示ASCII db db'$' assume ; ; int ;incdl dl,';intleadx,space calldis pop ;内层循环，cx ;leadx,r_c calldis poppopcx;loop_outcallexit yproc int21h yendpexitproc int21hexit enddatasegmentout1db'Enterkeyword:','$'out2db'Entersentence:','$'out3db'Matchatlocation:','$'out4db'Hofthesentence',13,10,'$'out5db'Nomatch',13,10,'$'keyworddbdbdb255dupsentencedbdbdb255dupkdbsdbdatacodesegmentassumecs:code,ds:data,es:datapushdssubax,axpushax leasi,keyword+2;sileadi,sentence+2;di
