the term "clear" is a bit vague - it may mean either of two things.

Assuming this is VB6 (don't know about later versions) you can use Erase to completely remove the array (so it no longer exists, doesn't take up any memory and cannot be used) or ReDim to simply clear the values but otherwise leave the array intact.
