Storing all the PID's in a variable.

Hi,

Code:
ps -ef|awk '{print $2}'

i want to store the result of the above command in a variable.
I never worked with arrays in shell scripting.
i tried the below code:
Code:
set a=`ps -ef|awk '{print $2}'`

But
Code:
echo $a

returns null.
I want to store the content in a variable and retrieve it line by line.
Please help me.
Thanks
