汇编实验报告(实验二)

实验二循环与子程序程序设计实验目的加深对循环结构的理解。掌握循环程序的设计方法。学习子程序的定义和调用方法。掌握子程序、子程序的嵌套、递归子程序和结构。掌握子程序设计、编制及调试。熟练掌握DEBUG的常用命令，学会用DEBUG调试程序。实验内容3）编制在屏幕上显示九九乘法表的程序。4）编制在屏幕上显示用*组成的三角形的程序。6）编写一个递归子程序，计算指数函数Xn的值，其中X，n从键盘输入。三、程序内容3）datasegmentdataendscodesegmentassumecs:code;ds:datastart:movax,datamovds,axmovbl,30hmovbh,31hmovcl,blone:addbl,1movdl,blmovah,2int21hmovdl,'*'movah,2int21hmovdl,bhmovah,2int21hmovdl,'='movah,2int21handbl,0fhandbh,0fhmoval,bhimulblmovah,0hmovch,0ahidivchmovdh,ahaddal,30hcmpal,30hjzthreetwo:movdl,almovah,2hint21hadddh,30hmovdl,dhmovah,2int21haddbl,30haddbh,30hmovdl,20hmovah,2int21hcmpbl,bhjlonemovdl,0ahmovah,2int21hmovdl,0dhmovah,2int21hmovbl,claddbh,1hcmpbh,3ahjlonejmpexitthree:moval,20hjmptwoexit:movah,4chint21hcodeendsendstart4）codesegmentassumecs:code,ds:data,ss:stackstart:moval,1movbl,1l:addal,30hmovdl,almovah,02hint21hpushaxmovdl,'*'movah,02hint21hpopaxpushaxaddbl,30hmovdl,blmovah,02hint21hpopaxpushaxmovdl,'='movah,02hint21hpopaxsubal,30hsubbl,30hpushbxpushaxmulblcallresultmovdl,''movah,02hint21hpopaxpopbxincalcmpal,bljbelmovdl,0ahmovah,02hint21hmovdl,0dhmovah,02hint21hcmpbl,8jakmoval,1incbljmplk:movah,4chint21hresult:movcx,0aaaa:movbx,10movdx,0divbxpushdxinccxmovdx,0cmpax,0jneaaaabbbb:popbxjmplastcccc:last:cmpbx,39hjaaboveaddbl,30hmovdl,blmovah,02hint21hloopbbbb
