请帮我看一下下列中少了什么！(20分)

如何使程序自动在某个固定文件夹下生成一个文本文件，并在文件中写入字符串（WIN98环境下）<br>以下的代码可以编译成功，并在WIN2K下运行良好，但是在WIN98下运行有错误！<br><br>&nbsp; &nbsp; &nbsp; &nbsp; createfile(pchar('c:/tem.txt'),0,0,NIL,create_always,file_attribute_normal,0);<br>&nbsp; &nbsp; &nbsp; &nbsp; assignfile(tem,'c:/tem.txt');<br>&nbsp; &nbsp; &nbsp; &nbsp; append(tem);<br>&nbsp; &nbsp; &nbsp; try<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;writeln(tem,'这是第一行！');<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;writeln(tem,'这是第二行！');<br>&nbsp; &nbsp; &nbsp; finally<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;closefile(tem);<br>&nbsp; &nbsp; &nbsp; end;

换一种方法试试:<br>s:TFileStream;<br>s:=TFileStream.create('c:/t.txt',fmCreate);<br>s.readebuffer() ; &nbsp;//加入你要加的东东<br>

接受答案了.
