AW: AVR Bascom Funktion in Delphi???

Was ist so schwer daran, sowas selber zu schreiben?

Delphi-Quellcode:
function Lookup(offset:integer; DataIN:string):string;
type
  TStatus = (sNone, sKommentar, sData);
var
  i, dataindex:integer;
  Status:TStatus;
  stop:boolean;
begin
  i:=1;
  Status:=sNone;
  dataindex:=0;
  Result:='';
  stop:=false;
  while (i < length(dataIN)) and not stop do begin
    if dataIN[i] = '''then begin
      if Status = sData then begin
        stop:=(dataindex = offset);
        inc(dataindex);
      end;
      Status:=sKommentar;
    end
    else if dataIN[i] = #10 then begin
      if Status = sData then begin
        stop:=(dataindex = offset);
        inc(dataindex);
      end;
      Status:=sNone;
    end
    else if (Status = sNone) and (copy(dataIN, i, 5) = 'Data ') then begin
      Status:=sData;
      Result:='';
      inc(i, 4);
    end
    else if Status = sData then begin
      if dataIN[i] = ',then begin
        stop:=(dataindex = offset);
        inc(dataindex);
        if not stop then
          Result:='';
      end
      else Result:=Result + dataIN[i];
    end;
    inc(i);
  end;
  Result:=trim(Result);
end;
Aufruf...
Delphi-Quellcode:
procedure TForm1.Button1Click(Sender: TObject);
var
  Liste:TStringList;
begin
  Liste:=TStringList.Create;
  try
    Liste.Append('''Data 25%');
    Liste.Append('Data 1%,25%,3%');
    Liste.Append('Data 100%,2%');
    Liste.Append('Data 100%,26%,64%,34%');
    ShowMessage('>' + Lookup(0, Liste.Text) + '<');
  finally
    Liste.free;
  end;
end;
