a text file question again

I have a file that looks something like this.

each row starts with

"XXXXXX,

where XXXXX is some numbers.. What I like to do is modify this number.

a 0 should be added to the end, then some zeros should be added to the start of the XXX until XXX has length of 14 numbers.

for example the row
"989534,2345,banana""""
should be:

"00000009895340,2345,banana""""

How can I do that?

Hi hulken,

function ConvertString(S: String): String;
var
  I: Integer;
begin
  I := Pos(',', S);
  Insert('0', S, I);
  while I <= 14 do
  begin
    Insert('0', S, 2);
    inc(I);
  end;
  Result := S;
end;

var
  S: TStrings;
  I: Integer;
begin
  S := TStringList.Create;
  S.LoadFromFile('filename');
  for I := 0 to S.Count-1 do
    S[I] := ConvertString(S[I]);
  S.SaveToFile('filename');
end;

hulken,

Try the following:

var
 Output: string;
begin
  // ...
  Output:= Format('%.14d,%d,%s', [Num1, Num2, 'banana']);
  // ...
end;
0
 
hulkenAuthor Commented:
Could you give me an example?.. The Format %.14d, will it add one 0 to the end and then fill the number upp with 0000  in the beginning until it's 14 char ?

Hulken,

Sorry, I forgot the trailing '0' on the first number. In that case, the following will work:

Format('%.13d0,%d,%s', [Num1, Num2, 'banana']);

And yes, it will pad the front with zeros, insert the number (to fill the 13 characters), then add a trailing zero to the first number, followed by the second number and a string, like this:

Output:= Format('%.13d0,%d,%s', [123456789, 4321, 'banana']);

will cause Output to now contain the string: "00001234567890,4321,banana"

?

s := s + '0';
while length(s) < 14 do s := '0' + s;
