Variable name as variable

[Anon]

Hi.

I want to have a dynamic variable.
I have set the following variables:
$test_1_2 , $a , $b .

Now I want to prepare a variable like
$test = $test$a$b . If $a is 1 and
$b is 2, $test should be = $test_1_2.

How can I do this? I don't really
know how to use the $$test_... stuff.

Thanks alot!
