Variable values within for loop

Hi All

I am trying to fetch the size of three files into three separate variables within a for loop and am doing something like this:

Code:
for i in ATT1 ATT2 ATT3
do
size_$i=`ls -ltr $i | awk '{print $5}'`
echo ${size_$i}
done

but am getting the below error:

Code:
ksh[3]: size_ATT1=522:  not found
ksh[3]: size_ATT2=2170:  not found
ksh[3]: size_ATT3=874:  not found

Any idea how to fix the "not found" error?

Thanks in advance
