procedure TForm1.Button1Click(Sender: TObject);
var
success: Integer;
sb: TChilkatStringBuilder;

begin
success := 0;

sb := TChilkatStringBuilder.Create(Self);

// Load a file that contains this string:  0123456789ABCDEF
success := sb.LoadFile('qa_data/txt/remove_chars.txt','utf-8');

// Remove "56789A" from the string.
sb.RemoveCharsAt(5,6);

Memo1.Lines.Add(sb.GetAsString());

// Output is: 01234BCDEF
