5）創(chuàng)建一磁盤文獻，保存從鍵盤輸入的字符串。6）編寫程序用設立系統(tǒng)時間，一方面從鍵盤以卜進制數(shù)形式輸入時間，然后修改系統(tǒng)時間，并重新以十進制形式顯示時間。7）編寫程序將屏幕分割成格狀，每一格涂上不同顏色，格數(shù)從鍵盤輸入。8）編寫程序在屏幕上顯示菜單，輸入相應菜單的序號后，選種該菜單項。三、實驗設備PC機一臺四、實驗環(huán)節(jié)。1）按程序流程圖編制實驗程序。2）輸入源程序。。3）匯編、連接程序，執(zhí)行程序，檢查結果。4）程序的執(zhí)行可用DEBUG的G命令,也可用T命令單步跟蹤執(zhí)行。五、源程序實驗五EXAM5-1STACKSEGMENTSTACKDB1024DUP（O）STACKENDSCODESEGMENTASSUMECS:CODE,SS:STACKSTART：MOVBL,0LP:MOVDL,2OHINT21HMOVAL,BLADDAL,0DAAANDAL,OFHMOVBL,ALPUSHBXORAL,3OHMOVDL,ALMOVAH,2INT2IHMOVBX,3E8HLP2:MOVCX,176H;延時1msLP1：PUSHFPOPFLOOPLP1DECBXJNZLP2POPBXINCBLJMPLPMOVAH2CODEENDSENDSTART執(zhí)行程序EXAM5—1?EXE,屏幕上依次循環(huán)顯示一個數(shù)字一個空格:0123456789
