There's no official way to walk the handle lists, but the method Memory
Peeker uses is *unlikely*, in my opinion, to break.  (My Nifty List CDA
depends on that, too.)

Yes:  you can do a PurgeAll(0).  It will return an error code, but it
will have done its job.  This feature appears starting in System 5.0.

Please note that Volume 3 is somewhat thicker than the first two volumes.
I don't know the ins and outs of their costs (and don't want to), but I
do know they aren't making lots of dough by selling Volume 3 for $35.
