Hi all, I have an associative array in awk that gets populated like this...

chr_count[$3]++

When I try to print my chr_counts I use this:

for (i in chr_count) {
    print i,":",chr_count[i];
}

But not surprisingly, the order of i is not sorted in any way. Is there an easy way to iterate over the sorted "keys" of chr_count?
