Re^6: multiple values per key

I still do not get it, @{$data1{$callid}} contains something like

INVITE   100  180  200
INVITE   503 ACK
[download]

so when I do below I expected results to be
INVITE100180200
INVITE503ACK
But instead I get scalar values in return.. why??

foreach $callid (sort keys %data1) {
     my @fields = join('', split(/[ +\t]/, @{$data1{$callid}}));
    print "@fields\n";
}

I was able to get it done using below.. Is this because reference is scalar? `foreach $callid (sort keys %data1) { my @fields = @{$data1{$callid}}; for my $element (@fields) { $element =~ s/\s+//g; print "$element"; } print "\n"; }` [download]	[reply] [d/l]
