Ah, my mistake. Hiperspaces are addressed differently from dataspaces and 
somewhere I thought I remembered that therefor they could be larger. Maybe to 
allow 24-bit applications to use 2 GB storage areas with hiperspaces?

I am still wondering what the current value of hiper- and dataspaces is, apart 
from being supported for older applications that were written to use them.

The DFSORT tuning pages state that they make a well calculated decision about 
using hiperspaces, dataspaces, 64-bit storage (addressable) and 64-bit objects 
(which's data must be moved to addressable storage to use it, like 
hiperspaces). Why not use 64-bit storage only, when it is available?

In my system I did see DFSORT use all 4 area's for its work space.
DFSORT people: please explain?
I'm not DFSORT folk, but I think, I can explain it.
Some time ago I was fighting with some job consuming to much memory. First I limited its storage with MEMLIMIT, but then DFSORT started using *spaces instead. Still a lot of memory. The conclusion is simple: DFSORT use any of the memory kind which is available, with some preferences of course. Details depend on availability or given resources.
