Hi David, The above explanation will hold only good if and only if the timers are in ascending order or descending order.Not ina random fashion which i missed to mention
Timer1 start --- > 10sec --- > 1sec,2sec,..........10 sec Timer2 start ---> 15sec ----> ........1sec, 2sec ...........................15sec Timer3 start ---> 05sec----->...............1sec,2ec..... Timer4 start ---> 45sec----->.................................1sec, 2sec.......... Timer5 start ---> 09sec----- >..............................................................1sec, 2sec.......... Will the above explantion holds good in this also ? can you please tell us. Regards Girish ............... Like this Timer1 and Timer2 will execute in parallel.
