But its seems a bit difficult to fetch the just previous value of dragy value since it calls a new value at every time step. I simply tried a swapping method. But it gets zero value. Could you please tell me whether is there any way to fetch the just previous value of a variable (from an array or something?) <br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Thanks regards<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Sijo GEORGE<br data-mce-bogus="1"></div></div></body></html>
