InputQuery example
This example uses a button and a label on the form. When the user clicks the button, the input box displays. If the user chooses OK, the string that appears in the edit box of the dialog box displays as the caption of the label on the form. If the user chooses Cancel, the dialog box closes and the caption of the label remains unchanged.
} 
procedure TForm1.Button1Click(Sender: TObject);
var
  NewString: string;
  ClickedOK: Boolean;
begin
  NewString := 'Default String';
  Label1.Caption := NewString;
  ClickedOK := InputQuery('Input Box', 'Prompt', NewString);
  if ClickedOK then            { NewString contains new input string }
    Label1.Caption := 'The new string is ''' + NewString + '''';
end;
