I have an array that I wish to reuse. Before I reuse it, I want to clear out all

elements. Both of the following seem to work:

    @an_array = "";

and

    $#an_array = -1;

I then go on to do something like:

    foreach (@foo_array) {
       push (@an_array, $_);
    }

Neither seems completely correct although I like the second. Is the second legal
and
portable or did I just luck out?

Is there a better way?
