RE: Sorting a Multi-occurrence data structure

["Fisher, Don" <Dfisher@xxxxxxxxxxxxxxxxx>]

Yes, I know, but how does QSORT determine which occurrences are passed to
the RPG procedure for comparison?  Does it make any assumptions as to the
position of the sort field?

For example, say I have a data structure containing four fields with values
as follows that I wish to sort by the third field:
B 1 DD 5
A 1 AA 6
D 2 BB 4
C 3 CC 2

If I use QSORT, it will presumably send the first two occurrences back for
comparison and my procedure will indicate occurrence one should come after
occurrence two.  Would it then present the third occurrence for comparison
with the first two?

I would think so, but I'm not sure based on what I've read.

You provide the procedure that qsort uses to compare elements in order to
sort the list.  The procedure you provide can use any element in doing the
comparison.
