Take a look at Don Lancaster's "Ask the Guru" column, November 1988,
Computer Shopper.  He defines his "snoop" command like this:

	/snoop {1183615869 internaldict begin} def % activates superexec

And describes it like this:

	"The snoop command will activate superexec for your use.  For
	instance, if a forall gives you an invalidaccess error, a
	{forall} superexec often will not.  The same trick will often
	work for {get} superexec.

	Calling snoop also does open up internal dict along with all
	its many strange and wonderous denizens.  Very handy.  And most
	interesting."

	[He goes on to describe the "hidden" FlxProc command.]

Now, does anyone have the decryptor "floating about?"  How about sharing?
