A simple way of emptying an array:
@some_array = ();

I'm not certain why it would keep the array indices. You can run this snippet to see what's
happening:
#!/usr/bin/perl -w
use strict;
use Data::Dumper;
my @array = qw(foo bar baz);
print Dumper \@array;
undef @array;
print Dumper \@array;
Can you show us a code snippet where you're having the problem?
Cheers,
Ovid
