Yes it is. > You have to call > SetLength(array, Integer) every time you want to assign a new element to it. You're still using the same variable over and over. And you don't *have* to call Setlength every time. You can call it once at the beginning with a large amount and then fill in that space as you proceed. Just like setting the length of a string, or the Capacity property of a list. > At the same time, the array itself is typed so you can't use it to hold more > than one element type AND it automatically deallocates memory if you delete > an element! The only way to delete an element is to use SetLength to truncate the array. If SetLength doesn't count as automatic handling of allocation, then it doesn't count as automatic handling of deallocation, either. Please see my article on how to delete elements from dynamic arrays: http://www.cs.wisc.edu/~rkennedy/array-delete -- Rob _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
