Not usre, it if works in VFP5.0(hopefully, it does):

lnModified=GetNextModified(0)  
         IF lnModified<>0 and lresp=0
              lresp=messagebox('Do you want to save changes?',36)  &&+32
         ENDIF
        IF lresp=7  && User requested that changes not be saved.
               =TABLEREVERT(.T.,THISFORM.laDE[i,1])
          ELSE            
               *=TABLEUPDATE(.T.,.T.)
               =thisform.dotableupdate()  && NSL 6/26/00
          ENDIF
