Re: [Harbour] Sorting the array
Hi,
asort(atst,{|x,y|x[2]y[2]})
what rule asort use in this case?
Just like always, it uses the 4th parameter of ASORT().

Yes of cause you are right, i'm not carefully read doc, but result is
same with asort(atst,,,{|x,y|x[2]y[2]})
before sorting
1 6.06 1 1
2 9.92 1 2
3 9.90 1 3
4 9.34 1 4
5 11.38 1 5
after sorting
1 9.90 1 3
2 6.06 1 1
3 9.34 1 4
4 9.92 1 2
5 11.38 1 5

I don't see any problem.
Harbour doesn't use a 'stable' sorting algorithm,
so it doesn't keep original order of identical keys.
I don't know what Clipper uses, but even if it
gives different results this is an implementation
detail, which app code should not rely upon.
All ASORT() guarantees is that keys will be ordered
as requested.
Extend your key if have some extra needs regarding
the ordering.
Brgds,
Viktor
