variable contains variable

[shaoji]

How could I put a variable as part of a variable? I know I can do this:

for i in a b c; do
eval a$i=foo$i
done
echo $aa $ab $ac

It will print out fooa foob fooc. But how could I get it using variable? I cannot use
echo $a$i
or
p=\$a$i
echo $p

any idea?

Thanks.

Something like this ?
for i in a b c; do
eval a$i=foo$i
done
for i in a b c; do
eval p=\$a$i
echo "p=$p"
done

Hope This Help, PH.
