in reply to pushing into arrays of arrays

Previous post about using references was right on. As a side note, though, if you're pushing an array that you reuse in a loop, you'll want to create a new, anonymous array reference each time through. E.g. 

while ( @array = somefunc() ) {
    push( @aoa, [ @array ] );
}

To your second question, yes, that should work.

    Thanks for the replies;

    I have a problem with references in that I was specifically hoping to create a copy of the array. The code works a bit like this; 
    loop
    loop
        calculate @values
    end loop
    push @values into @sets for use later
end loop

      Just read the post from xdg above your post again. He just pointed out, that you could use copies in such a case using

      push @array, [ @localarray ]

      instead of

      push @array, \@localarray

        Hmm..,

        I'm using the following to read through all of the pushed arrays and list their lengths, but it is returning length -1 each time.. 
        foreach $ary (@arrays)
{
    print $#{ary};
}
