Hello Wise Ones, I have a question about foreach syntax. I'm iterating over each key in a hash: 
 for my $p9 (keys %is_available) {

[download]
Now, I'd like to only iterate over the keys with a nonzero value. In effect, I'd like to do this: 
 for my $p9 (keys %is_available) {
  if ($is_available{$p9}) {

[download]
But I'd like to make it as efficient as possible by putting the nonzero value constraint in the foreach line. Many thanks in advance, Jim
