Awk output to bash array?

I there any way to output the awk output to a bash array?

For example

a = awk -F: '{print $3}' myfile

10 20 30 40 50
20 30 40 50 60
90 80 70 60 50

a[0] = 30 40 70

So that
a[1] = 30
a[3]= 70

or something similar

echo ${arr[*]}

@OP, depending on what you wish to do, you can do everything in awk, no need to return values to bash.
awk '{a[++d]=$3}END{for(i=1;i<=d;i++){print a[i]} }' file

Thanks guys!

Yes I do know that I can do everything in AWK. but I want to avoid using system() if I can. Unless there's a way to test for the existence of a directory within awk NOT using system().
