Perl database connection

The following string works correctly, opening a connection to my current SQL server database:
my $dbh = DBI->connect('dbi:ODBC:DRIVER=SQL Server;
                                    APP=Microsoft Data Access Components;
How can I substitute a variable that contains the db connection string?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would do something like this, allowing to easily see all the parameters and change them easily:
my @dbcon;
push(@dbcon, "dbi:ODBC:");
push(@dbcon, "DRIVER=SQL Server;");
push(@dbcon, "DATABASE=DB1;");
push(@dbcon, "APP=Microsoft Data Access Components;");
push(@dbcon, "Trusted_Connection=No;");
push(@dbcon, "SERVER=ABC;");

my $dbh = DBI->connect(join('', @dbcon),"$DBuser","$DBpw");
