from the pod:

		Turn logging on or off

I wondered about double-MacPacking (who hasn't?) and so I wrote this
little program:

#!perl
use Mac::Types;

$a = "0";
$b = "1";

# show the ord() of the MacPacked values
print "0 MacPacked: ", ord(MacPack('bool',$a)), "\n";
print "1 MacPacked: ", ord(MacPack('bool',$b)), "\n";

$c = MacPack('bool',$a);
$d = MacPack('bool',$b);

# show the ord() of the doubly packed values
print "0 MacPacked again: ", ord(MacPack('bool',$c)), "\n";
print "1 MacPacked again: ", ord(MacPack('bool',$d)), "\n";

exit(0);

RESULTS IN:

0 MacPacked: 0
1 MacPacked: 1
0 MacPacked again: 0
1 MacPacked again: 0

So this explains why typeTrue does nothing: it becomes reMacPacked into
typeFalse! What it doesn't explain is why sending 0 instead of typFalse
AppleProds WebSTAR into saying ouch...

Oh, well. I think you may want to do some checking in Glue anyways - for
whether or not a boolean has already been MacPacked.
