SQL - the FOR in a SELECT statment

Hello,

There is a select statement with a FOR in it which I do not know what it is for. Can anyone help. Here is a sample:

	select no
	       , act


		, status


		, ref1


		, ref2


	      into cur_act
	      from act
	     where no = act_no
	       for update of status;

Thanks,
