while문에서 잠깐 멈추는건            
Application.ProcessMessages;
            sleep(1);
이것으로 알았습니다... 만약 잠깐 멈추었다 다시 멈춘부분부터 시작하려하는데 continue 를 타지않는데요..
왜 그런것일까요??



while not eof( f ) do begin
        s := '';
        Readln(f,s);          
        xx := copy(s,1,5);

        if (strtoint(xx)) > j then
        begin
            kkk := '';
            kkk := Trim(s);
            UDF_DB_Insert(Trim(kkk));
            StopPoint := xx;
        end;
            //잠시멈춤
            Application.ProcessMessages;
            sleep(1);

        if CheckBox1.Checked = true then begin
            break;
        end else begin
            continue;
        end;

        inc(i);
    end;
