Dear Experts

I create abc.exe with following xyz.prg

_SCREEN.VISIBLE = .F.
set talk off
set resource off
SET Default To (Sys(5)+Alltrim(Sys(2003)))
messagebox("Processor Serial is ...",0+32,"Serial No")
READ Events
_SCREEN.VISIBLE = .T.

The Messagebox appears correctly but when I press OK
then messagebox disappears and VFP remains open.

How to QUIT VFP from background?
What more codes should I write in xyz.prg

Thanks
