Hello there...

I have a simple question (I guess...).
I have an array with two columns and a thousand of rows. Each row has a

pair of latitude and longitude.


Array=floatarr(2, 1000)


-27.3456 -54.6529
-23.4546 -56.7263
... and so on...


I need to retrieve only 100 pairs, randomly. How can I do that?
Any comments welcome!
Julio

I hadn't realised this is such an interesting problem... thanks for
that. Are you using this for something?

regards,
Greg
