Thank you TonHu.
SetCancel() will do the trick. Sorry for the misplaced word "between" in last post. I´m not a native english/american guy. I´m brazilian, so, sometimes words may go wrong in text.
One more comment. This "Clipper" forum is almost completely inactive. Where do the Harbour users go for help? I mean real valuable help from experienced people like you, fBizell, JockMullin, GriffMG and others?
