RE: Sorting a user space

To order data in a User Space I built an array of pointers to each
entry, then sorted the array as desired:

D                       DS              Align
D PtrAry                32      Dim(100)
D ThePtr                  *   Inz(*Null) Overlay(PtrAry:1)
D The1stSortField        2A   Overlay(PtrAry:17)
D The2ndSortField        2A   Overlay(PtrAry:19)
D Filler                12A   Overlay(PtrAry:21)

(The filler is used to keep the pointers aligned on 16 bit boundries)

Once I've filled the array with pointers and data, I can sort by either
sort field and then retrieve the corresponding User Space entries -
thereby 'sorting' the user space

Hope it helps

The list api's use a user space.  I suppose I could read from the user 
space, write out to a user index and then load the subfile from the
keyed 
user index.
