# 3.)  Use Apple Event handlers in MacPerl to return more than one piece
# of data by, for example, returning an AE list.  Here is an example.  Run

I should have noted how you might want to have a list of lists.  Here you
are.  Using the same AppleScript as before, you get the result:

    {{"2.4000001", "2.4000001", "4.8000002"}, {"2 + 2 = 5"}}

#!perl -w
use Mac::AppleEvents;
my($ok);

# set handler for app McPL and event id DATA
$AppleEvent{'McPL', 'DATA'} = \&RecData;
print "Starting ...\n";
while(!$ok){sleep(1)}
print "Done.\n";

sub RecData {
  my($event, $reply, $desc, $n, $list1, $list2, $list3) = @_;
  $desc = AEGetParamDesc($event, keyDirectObject());
  $n = AEPrint($desc);
  $list1 = AECreateList('',0);
  $list2 = AECreateList('',0);
  $list3 = AECreateList('',0);
  AEPut($list1, 1, typeChar(), $n);
  AEPut($list1, 2, typeChar(), $n);
  AEPut($list1, 3, typeChar(), $n+$n);
  AEPut($list2, 1, typeChar(),
    sprintf('%.f + %.f = %.f', $n, $n, $n+$n)
  );
  AEPutDesc($list3, 1, $list1);
  AEPutDesc($list3, 2, $list2);
  AEPutParamDesc($reply, keyDirectObject(), $list3);
  print AEPrint($event), "\n";
  print AEPrint($reply), "\n";
  AEDisposeDesc($desc);
  AEDisposeDesc($list1);
  AEDisposeDesc($list2);
  AEDisposeDesc($list3);
  $ok = 1;
  0;
}
