In the sub below I want to pass an aditional parameter, which will tell based on which field in the string with | delimeter sorting will be done. I tried to use @_ but experienced problems. I want something like my @sorted_xx = sort sorter (@xx, $sorting_field); Probably I want what is impossible. Thanks, Vitaly
---------------------------------------------------- 
my @xx = ( 'dfb|cy|nmju', 'dfb|my|jhiho', 'aaa|zz|gggg' );
my @sorted_xx = sort sorter @xx;

print Dumper \@xx;
print Dumper \@sorted_xx;

sub sorter {
    my @arr_a = split /\|/, $a;
    my @arr_b = split /\|/, $b;
    while ( @arr_a ) {
        my $sa = shift @arr_a;
        my $sb = shift @arr_b;
        my $comparison = ( $sa cmp $sb );
        return $comparison if $comparison;
    }
    return 0;
}
