Hi,

i search a possibility to sort an array with more than one key (like an ORDER BY X, Y in SQL). I have searched the whole internet after this information, but without any help ...

I have a random-file, with more than 200.000 records. The quicksort-routine for one key is very fast and no problem. But i need more: I have 3 values

ID,LAT,LONG

And now i want to sort the LAT AND!!! the LONG values tougether, because some LAT values are equal.

Hope i found here a answer of my question ... and a solution of my project (which is stopped since over a week, due this problem )

Thanks,

Richard
