Storing command output in an array

Hi,
I want keep/save one command's output in an array and later want to iterate over the array one by one for some processing. instead of doing like below-
Code:
for str in `cat /etc/passwd | awk -F: '$3 >100 {print $1}' | uniq`

want to store-
Code:
my_array[] = `cat /etc/passwd | awk -F: '$3 >100 {print $1}' | uniq`

and then want to do-
Code:
for str in my_array[]
do
...
done

shell is korn shell, sorry for syntax mistakes.

thanks in advance.Smilie
