Hi Annett;

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

  #!/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?
