Perhaps it'd be better to invest into a somewhat more generic parser, something like this:

my (@records,$cur);
while(<>) {
    chomp;
    if ($_ eq "//") {
        push @records, $cur if defined $cur;
        $cur = undef;
    }
    elsif (/^(.+?) - (.+)$/) {
        my ($key,$value) = ($1,$2);
        if (defined $cur->{$key}) {
            if (ref $cur->{$key})
                { push @{$cur->{$key}}, $value }
            else
                { $cur->{$key} = [$cur->{$key}, $value] }
        }
        else
            { $cur->{$key} = $value }
    }
    else { warn "didn't handle input line: $_" }
}
push @records, $cur if defined $cur;

Note that changing @records into a hash keyed by UNIQUE-ID is as simple as my %records = map {$_->{'UNIQUE-ID'}=>$_} @records;
