I'm not sure I follow. You can tighten that up a little & make it a bit
more Perl idiomatic with something like:
foreach $i (@array) {
# do something with $i
# then if appropriate...
print $another_array[$i];
# or, perhaps better, perhaps not, use a hash:
print $another_hash{$i};
}
But I'm not sure if this gets at what you're getting at...
