I have a data structure array that I am sorting using qsort and I'm
observing some 'unintended' sorting going on and thought I'd see if
someone else has seen this.
 
My data structure array contains 9 fields, one of which is a status
field (1.0) which is what I am using to sort by...I want to see the
higher status' last.  When I load up the ds array only two rows contain
a status other than 0.  When qsort is called, the ds array comes back
with the higher status' last, however, those that have a status of zero
are also re-ordered amongst themselves.  Does any body know why that is?
I would think that if there is no difference in the value of status,
then these would not be 'touched'.
 
The sorting code is pretty standard, but here's some of it...
 
The ds array...
 
Drsw              ds                  qualified dim(9999) based(w)
D acctn                         16  0                                  
D acctt                          1                                     
D prod                          20                                     
D tax                            9  0                                  
D accts                         20                                     
D curr                          11  2                                  
D rela                           1                                     
D relad                         10                                     
D status                         1  0                                  
 
 
The comparison code used by qsort...
 
C                   select                                        
C                   when      element1.status < element2.status 
C                   return    -1                                  
C                   when      element1.status > element2.status 
C                   return    1                                   
C                   other                                         
C                   return    0                                   
C                   endsl                                         
 
 
 
Thanks in advance,
Dane
