You can instantiate a container of whatever size, but to find out where the valid data is, you'd be better off maintaining an index, and increment or decrement it when you add or remove data.
What language are you using?

How about
<html><head><script language="javascript1.2">
var arr = new Array(); for(var i=0; i < 5; i++) { arr.push(i); } alert(arr.length); arr.pop(); alert(arr.length);
</script></head><body></body></html>
That sort of thing will give you the length of your significant data.
Look into shift and unshift as well as they work on the first element in the array whereas push and pop work on the last element.
