Using $ in a word

I want to read some registery data, but the name of the key is:
$(MsSqlServerDataSourceName)

Now when i try to compile it says, (MsSqlServerDataSourceName)
variable found..

Is there some wildcard to say its a string not a var, like \$(MsSqlServerDataSourceName)?

Have you tried $$
