Reset

[Lucas]

I have a dialog with some controls:

case 19
_s=""
_s.setwintext(id(3 hDlg))
_s.setwintext(id(4 hDlg))
_s.setwintext(id(5 hDlg))
_s.setwintext(id(10 hDlg))
_s.setwintext(id(15 hDlg))
_s.setwintext(id(16 hDlg))
_s.setwintext(id(17 hDlg))
_s.setwintext(id(18 hDlg))
estan=""
noestan=""

Is there any way to reset controls and variables with one function?
or reset int variables;str variables...?
