Hi All,
I'm editing a script that has the following: 
my @missing;
foreach my $f (@fields) {
  if ($account{$f} eq undef) {
    push(@missing, @acct_fields{$f});
  }
}

I understand what this is doing, but the following part that throws me off...although i can assume what it's doing i want to know how it actually works: 
if ($#missing > -1) {
  $" = ', ';
  do something....
}

Thanks in advance for your help.
