difference between $AAA and ${AAA}

I am a little confised about some issue: when should one use the ${AAA} and when the $AAA? What is the difference?

Thx,
Viv

The difference is that $AAA uses a variable. Therefore, $AAA can be set at run-time of the installer, as well as changed during execution. ${AAA}, however, is used to access the value of a define, which is set at compile-time of the installer. Therefore, the value in ${AAA} can never be changed during run-time of the installer.
