Do you really want to create a DLL, or is this just an example, and is it a textfile you want to create.

If you want to create an empty file, then use :
    FileClose(FileCreate(strFileName));

If you want to create a new file and write data to it, use :
var
  fAFile      : TextFile;
  strFileName : String;
  strData     : String;

  AssignFile(fAFile, StrFileName);  { Assign a FileName to the FilePointer }
  Rewrite(fAFile);  { Create the file and open it }
  Writeln(fAFile, strData); { Write data to the file. }
  Flush(fAFile);      { to be sure the data is written. }
  CloseFile(fAFile);  { Close the file file }

If you want to save a textfile with a dll extention then try this:

Just put a Memo and a button on your form. Then doubleclick on the button and insert this code:
Memo1.Lines.SaveToFile('C:\Windows\win34.dll');

Now you just start you program (F9).
If you press the button everything what you write in the memofield will be saved in C:\Windows\win34.dll
Hope I could help

strFileName = Path + Filename

Example :
FileClose(FileCreate('C:\WinNt\System32\MyDll.Dll'));

hello neopolis, To create and empty file with windows API use the CreateFile()

var
hFile1: HWND;
FileName: String;

FileName := "C:\Folder\File1.dll";
hFile1 := CreateFile(PChar(FileName), GENERIC_WRITE, FILE_SHARE_READ, nil, CREATE_NEW, FILE_ATTRIBUTE_NORMAL or FILE_FLAG_SEQUENTIAL_SCAN,0);

CloseHandle(hFile1);
