hi,
i want an array , i dont know how many objects are going to be added to it before the function call, so is there anyway to

* increase the upperbound, then add the new object?
or
* i know i'm not going to have more than 20 objects, so can intsiate it with 20 objects, then remove the extra one ( empty values) at the end?

what i finally want is a full array, no empty values


thanks...
