. /data.file
anum=0 <-- Since this is meant as an integer you should not quote it
while [ ! -z "${sg_name[${anum}]}" ]
do
echo "sg_name[${anum}]}"
echo "sg_size[${anum}]}"
echo "sg_allow[${anum}]}"
((anum++)) #<-- You did not increment the anum value
done

I see, I was trying to type fast and missed the increment line...

Something I didn't realize though is "not quoting" if the variable is suppose to be an integer.

I usually typeset the variables in my scripts to declare them as integers.

typeset -i anum

In this case, if I set:

typeset -i anum
anum="0"

Does quoting over ride the typeset?
