Dear All,

I was using code that I found on PerlMonks page but can't seem to figure out how to use it. I have a set of hash reference created with;

$idx = 0;
 
foreach $n (@IDs) {

push @{$An{$n}->{b}} , $bb[$idx];
push @{$An{$n}->{c}} , $cc[$idx];
push @{$An{$n}->{e}} , $ee[$idx];
push @{$An{$n}->{d}} , $dd[$idx];
push @{$An{$n}->{f}} , $ff[$idx];
    
$idx++;
    
}

How can I then for each $ID print values of corresponging position? Such as $ID[0], @{$An{$n}->{b}}[0]? etc. Btw is it a better practice to declare arguments with 'my' at the begining or just in code? I end up with a code ehader having declaration of 40+ variables (not always possible to do subs). Thanks for help.
