Results of Bunge and Funk and of Johnstone, providing constructively s
ound descriptions of the global points of the lower and upper powerloc
ales, are extended here to describe the generalized points and proved
in a way that displays in a symmetric fashion two complementary treatm
ents of frames: as suplattices and as preframes. Also described here a
re the points of the Vietoris powerlocale. In each of two special case
s; an exponential $(D) ($ being the Sierpinski locale) is shown to be
homeomorphic to a powerlocale: to the lower powerlocale when D is disc
rete, and to the upper powerlocale when D is compact regular.
