If static variables bother you, use your 
favorite technique to save the state 
of lAlign without using a static variable.
*/

// toggles alignment. This assumes
// that the TA_CENTER alignment is 
// not supported

// Do this when the user toggles reading
// order
lAlign ^= TA_RTLREADING ;

// 
// Before calling ExtTextOut, (e.g., when
// processing WM_PAINT messages), do the
// following:
SetTextAlign (hDc, lAlign) ;
