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?
