Using Writeln to create text file in delphi

I am using Writeln for create a text file in delphi 5 and packing it to 628 charactors
The writeln option adds a CRLF at the end of each line (as far as I have read)
error .. On some computers the last line looses the CRLF

txtline := 'Testline1';
l := length(txtline)
for i := l to 628 do begin
    txtline := txtline + ' ';
end;
txtline := 'Testline2';
l := length(txtline)
for i := l to 628 do begin
    txtline := txtline + ' ';
end;

any suggestions how I can fix this

only use the write instead of writeln
the file ends with #26

I am not sure what #26 is

#26 is the End Of File marker

did you try the TStringList approach ?
and the format routine ?




procedure CreateGovFile(FileName: string);
var List: TStrings;
begin
  List := TStringList.Create;
  try
    List.Add(Format('%-628.s', ['TestLine1']));
    List.Add(Format('%-628.s', ['TestLine2']));
    List.SaveToFile(FileName);
  finally
    FreeAndNil(List); 
  end;
end;
