in reply to Dynamically Assigning 1 array to another

You think you do, but you really want a hash of arrays. Read perlreftut and then see perldsc.

    OK. So I'm having some problems with dereferencing.
    I am trying to iterate through the items with this..


    foreach my $servers (@{$masterlist{$servtype}}){
    print "Let's see $servers \n";
    print RESULT " members $servers".":$serviceport\n";
    }


    When $servtype is explicitly defined it works fine, at least for that array. But when I put $servtype in there it doesn't work.
    The $servtype variable has the same values as the array name. It SHOULD work but I must be dereferencing something improperly.

my %masterlist = (
    foo => [ 1, 2, 3, ],
    bar => [ 'a', 'b', 'c', ],
);

my $servtype = 'bar';

for my $servers (@{$masterlist{$servtype}}) {
    print "$servers\n";
}

    I hadn't thought of that. Yeah that makes more sense. Thanks!
