You can do this by useing multilevel data structures.

An example would be:

$tmp="foo"
${$tmp} = "newdata";

You can also use:

$tmp="foo"
${"$tmp"} = "newdata";


Note by Colin Thomsen:

You can also do:

$tmp = "foo";
$$tmp = "newdata";
print "$foo\n";

This shows that $$tmp is equivalent to $foo
