Yes, that is true Aaron. Thank you for the clever answer! I'm not quite sure how it works, so I'll have to run this in a few test scripts.. Your feedback is greatly appreciated :)

You're welcome. The confusing part there might be the ternary operator, which you can learn more about in perlop, under Conditional Operator. It's more-or-less an if-then-else conditional, but since it's a single expression, it's easier to plug into a print statement like that. If Perl didn't have it, I'd probably do the same thing with something like this:

{                                      # start a block to limit the va
+riable's scope
  my $maybe_a_slash = '';              # default to no slash
  $maybe_a_slash = '/' if $i;          # make it a slash if counter ha
+s incremented
  print "$a[$i]$maybe_a_slash$c1[$w]";
}                                      # end the block
