汇编语言课设文本编辑器

题目：文本编辑器 ... 1.2 .2.1开发背景...........................................3.3数据定义............................................4模块设计.......................................... 4.1运行结果...........................................4.2结果分析.............................................1程序测试..............................................................................摘要文本编辑器在我们的日常生活中使用非常频繁，是我们工作当1.2设计的内容的界面；2.在文本编辑区可以随意输入字符；4.实现了光标上移、下移、左移、右移；5.实现了下拉菜单以及弹出式菜单；6.可以实现屏幕的上卷和下卷；.1开发背景本次开发主要是在《微机原理与接口技术》这门课学习完成之2.2程序设计的意义本程序主要利用BIOS功能调用设计编辑器的菜单和编辑窗口，3.1总体设计方案程序利用模块化设计方法，对每个要实现的功能都设计成子程序，方便使用。程序中具体模块如图3-1。主程序绘制界面按键判断子菜单绘功能的实displaydis_edit3.2实现过程display(显示菜单栏);dis_edit(显示编辑窗口);dis_file(显示文件菜单);dis_text(显示文本菜单);key_down(光标向下);key_left(光标向左);key_up(光标向上);key_right(光标向右);key_pgup(菜单的循环选择);ok_exit(退出);open(子菜单显示及控制);.3数据定义好了，由于功能调用的需要所以把数据定义在了数据段和附加段中。以下是程序中用到数据的定义：datasegmentsdb'FileViewTextAbout$'f1db'Open',10,13,'Exit',10,13,'$'f2db'Clear$'idb0bdb0buffdb1200dup(?),'$'printfdb"Can'topentheFile$"mssdb'Massage$'ab1db'AboutEdit$'ab2db'GaoHaiFeng$'ab3db'C1141$'ab4db'2013-6-22$'dataendseatasegments1db'File$'s2db'View$'s3db'Text$'s4db'About$'s5db'Open$'s6db'Exit$'s7db'Clear$'eorrdb'eorr:$'okdb5bh,'OK',5dh,'$'designdb'Design:$'classdb'Class:$'datedb'Date:$'qqdb'QQ:$'eataends事先定义好数据的结构可以减少程序设计中很多的麻烦。块设计开开始绘制编辑绘制菜单返回3.4.2检测按键开始AH=0?是否返回3.4.3子菜单绘制该模块同样采用了BIOS功能调用设置子菜单，具体操作见图制返回4.1运行结果4.2结果分析选择、光标的移动、5.1程序测试通过本次课程设计可以说收获颇多，虽然在程序设计的过程中七、参考文献月datasegmentsdb'FileViewTextAbout$'f1db'Open',10,13,'Exit',10,13,'$'f2db'Clear$'idb0bdb0buffdb1200dup(?),'$'printfdb"Can'topentheFile$"mssdb'Massage$'ab1db'AboutEdit$'ab2db'GaoHaiFeng$'ab3db'C1141$'ab4db'2013-6-22$'dataendseatasegments1db'File$'s2db'View$'s3db'Text$'s4db'About$'s5db'Open$'s6db'Exit$'s7db'Clear$'eorrdb'eorr:$'okdb5bh,'OK',5dh,'$'designdb'Design:$'classdb'Class:$'datedb'Date:$'qqdb'QQ:$'eataendsstacksegmentdw1000dup(?)stackendscodesegmentassumeds:data,cs:code,ss:stack,es:eatamovds,axmovax,eatamoves,axmovah,0moval,3int10hcalldisplay;显示菜单栏calldis_edit;显示编辑区movah,4chthdisplayprocnear;显示菜单栏movah,6moval,0movch,0movcl,0movdh,0movdl,79movbh,70hmovmovmovmovmovmovmovmovmovmovmovmovretdisplayah,6al,1hlhdl,79bh,70hah,2bh,0hlah,09hsdis_editprocnear;显示编辑区movmovmovmovmovmovmovmovintmovmovmovmovmovmovmovpgup_r:di,0;作为缓存指针ah,6al,0hldh,24dl,79bh,1ehah,6al,1hldh,24dl,79bh,1ehmovah,2movbh,0movdh,1movdl,0int10hnext:movah,00h;从键盘读取字符int16hcmpal,1bh;判断输入的字符是否是ESCjzexitcmpal,0dhjzentercmpah,48h盘扫描码jzdi_upcmpah,4bhjzdi_leftcmpah,4dhjzdi_rightcmpah,50h;判断输入的字符是否是回车;判断按键是否是上,ah中存放的是特殊键jzdi_downjzdi_pgupcmpah,0ehjzdi_backmovbuff[di],al;每次接收一个字符时都存放到BUFF中imovbuff[di],'$'movah,2thloopnextjmpnext1;这里相当于无限循环,CX的值不起作用ffdiimovbuff[di],13imovah,3;获取光标位置movbh,0int10hcmpdh,24;判断回车之后是否是行尾jzgo_againmovmovincmovintah,2bh,0lnext1jmpnext1di_left:callkey_left;调用左移子程序jmpnext1di_right:callkey_right;调用右移子程序jmpnext1di_down:callkey_down;调用下移子程序jmpnext1jmppgup_rdi_back:callkey_backjmpnext1go_again:calldis_loop;上卷一行定位到行尾jmpnext1exit:movah,6moval,0movch,0movcl,0movdh,24movdl,79int10hretdis_editendpdis_loopprocnear;编辑区上卷一行光标定位到行尾movah,6moval,1movch,1movcl,0movdh,24movdl,79movbh,1ehint10hmovah,2movbh,0movdh,24movdl,0int10hretdis_loopendpkey_upprocnearmovah,3;读取光标位置movbh,0int10hcmpdh,1jzrodownmovah,2;定位光标位置decdhint10hreturn:retrodown:callroll_downjmpreturnkey_upendproll_downprocnear;屏幕下卷movah,7moval,1movch,1movcl,0movdh,24movdl,79movbh,1ehint10hmovah,3;读取光标位置movbh,0int10hmovah,2;定位光标位置int10hretroll_downendpkey_leftprocnearmovah,3;读取光标位置movbh,0int10hcmpdl,0;判断是否到了第一列jzgo_left;是的话移到上一行行尾movah,2movbh,0decdlint10hjmpret1go_left:cmpdh,1jnzroll_upmovah,6moval,1movch,1movcl,0movdh,24movdl,79movbh,1ehmovmovmovmovintah,2bh,0dl,79hret1roll_up:movah,2;移到上一行行尾movbh,0decdhmovdl,79int10hret1:retkey_leftendpkey_rightprocnearmovah,3;读取光标位置movbh,0dl,79go_rightdh,24on_okmovah,6moval,1movhmovlmovdh,24movdl,79movbh,1ehmovah,2movbh,0movdh,24movljmpret2movbh,0movret2go_right:movah,2movbh,0lint10hret2:retkey_rightendpkey_downprocnearmovah,3movbh,0dh,24m_downmovah,6moval,1movhmovlmovdh,24movdl,79movbh,1ehmovah,3movbh,0movah,2movbh,0movdh,24ret3m_down:movah,2movbh,0hint10hret3:retkey_downendpkey_pgupprocnear;按下pgup键的处理过程st_pgdn:calldisplaycmpi,0jnznt;判断当前的菜单项是第几个movah,6;菜单项处清屏moval,0movbh,1fhmovch,0movcl,0movdh,0movdl,3int10hmovah,13hmoval,0movcx,4movdh,0movmovmovleaintjmpnt:cmpjnzmovmovmovmovmovmovmovintmovmovmovlbl,0a5hbh,0bp,s1ret0nt1bh,1fhah,6al,0hlhdl,12ah,al,0xmovmovmovmovleaintjmpnt1:jnzmovmovmovmovmovmovmovintmovmovhlbl,0a5hbh,0bp,s2ret0cmpi,2nt2bh,1fhah,6;小菜单清屏al,0hcl,18hdl,21ah,13hal,0movmovmovmovmovleaintjmpnt2:jnzmovmovmovmovmovmovmovintmovxhdl,18bl,0a5hbh,0bp,s3ret0cmpi,3nt1bh,1fhah,6al,0hcl,27hdl,30ahhbios输出字符串movmovmovmovmovmovleaintret0:cmpjnzmovrtt:al,0xhdl,27bl,0a5hbh,0bp,s4incirttmovah,0hah,49hst_pgdnal,0dh;判断是否是回车rt0jnzlolcalldis_aboutjmprt0lol:cmpi,1jnzqqqcalldis_filejmprt0qqq:cmpi,3jnzrtt;不确定calldis_textrt0:cmpi,1jnzntfmovah,6;菜单项处清屏moval,0movbh,70hmovch,0movcl,0movdh,0movdl,3movmovmovmovmovmovmovleaintjmpntf:jnzmovmovmovmovmovmovah,13hal,0xhlbl,70hbh,0bp,s1rrrcmpi,2ntf1bh,70hah,6al,0hlhmovintmovmovmovmovmovmovmovleaintjmpntf1:jnzmovmovmovmovmovdl,12ah,al,0xhlbl,70hbh,0bp,s2rrrcmpi,3ntf2bh,70hah,6;小菜单清屏al,0hcl,1
