i:=0;<br> <br> while (a[j] <>＃0) do begin<br> <br> b[i]:=a[j];<br> <br> if (j mod 2=1)and(j>0) then begin<br> <br> Inc(i); b[i]:=＃13;<br> <br> end;<br> <br> Inc(j); Inc(i);<br> <br> end;<br> <br> b[i－1]:=＃0;<br> <br> result:= strpas(b);<br> <br> end;<br> <br> <br> 最后添加Form1的OnCreate事件。注意：要在uses子句中添加单元名称stdctrls。<br> <br> procedure TForm1.FormCreate(Sender: TObject);<br> <br> var<br> <br> labary:array[0..6] of Tlabel;<br> <br> i:integer;<br> <br> begin<br> <br> for i:=0 to 6 do<br> <br> begin<br> <br> labary[i]:=Tlabel.Create(self);<br> <br> labary[i].parent:=self;<br> <br> labary[i].caption:=convertstring(poemary[i]);<br> <br> labary[i].top:=(form1.Height－labary[i].height) div 2;<br> <br> labary[i].left:=10＋i＊33;<br> <br> end;<br> <br> end;<br> <br> 此程序在Windows 95，Delphi3.0环境中运行通过。 </td> </tr></tbody></table></center></div><hr align="center" SIZE="1" width="700"><p align="center" class="ourfont"><span><span><font color="#000000"> <a style="color: rgb(0,0,0);
