Delphi-Quellcode:

var
  fMyFile  : file of Integer;
  fileName : string;
begin
  fileName := ...irgendwas
  AssignFile (fMyFile, fileName);
  if FileExists (fileName) then
    begin
      Reset (fMyFile);
      Seek (fMyFile, FileSize (fMyFile));
    end
  else
    rewrite (fMyFile);
  try    
    BlockWrite (fMyFile, MyFile [1], 7);
  finally
    CloseFile (fMyFile);
  end;
end;
