script USE help

I have a script that has a local variable called @.DB which holds the name of
the database to use, like this:
DECLARE
@.dbname varchar (256);
set @.dbname = 'DBNAME_REPLACEONINSTALL'
Our GUI installation modifies the value of this script. This is validated by
testing the value of the variable, using:
IF @.dbname like '%REPLACEONINSTALL%'
RAISERROR('Script is invalid. Must be run through GUI installer or local
variables at top of script must be replaced manually. Exiting database
create', 20, 1) WITH LOG;
else
select 'Script validated, proceeding' as STEP;
I then issue the USE command, using:
use @.DBNAME
DDL SQL..
DDL SQL..
DDL SQL..
The script fails due to this:
Server: Msg 170, Level 15, State 1, Line 7
Line 7: Incorrect syntax near '@.dbname'.
I am guessing that you cannot use local variables in a USE command. Is this
true?

That is correct... You'll probably have to use dynamic SQL with the USE and
the DDL in a single batch.
