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 complete
proper way:
@an_array = ();
or
undef @an_array; # doesn't really free up the memory it used but the array
is uninitialized

This does not clear out all elements, it assigns one element to
@an_array with the value of "".

you can always set it to undef also:
@an_array=undef;
