nested variables

Shell Programming and Scripting

Is there any way to do variable nesting using sh?

For example:

example_1="a test string"
example_2="another test"
example_3="etc..."
i=2

echo ${example_$i}

The shell reports:
sh: ${example_$i}: bad substitution

If not, maybe someone could suggest another method. Thanks in advance.

$ example_1="a test string"
$ example_2="another test"
$ example_3="etc..."
$ i=2
$ eval echo \$example_$i
another test
