Create database using script at the default path?

I've generated a script of a database in SQL Server 2008. The generated script has the hardcoded path of where the database would be created. I don't want this path to be hardcoded, I want this path to use the default of the database engine the script is running on.

Here is the small portion of the script:

CREATE DATABASE [POS] ON  PRIMARY 
( NAME = N'POS', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\POS.mdf' , SIZE = 2048KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'POS_log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\POS_log.ldf' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO

The path C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\POS.mdf might not exist on all computers that's why I want it to be chosen by the database engine

Simply create the database and then adjust all the needed properties directly in files

CREATE DATABASE [POS] 
GO
ALTER DATABASE POS MODIFY FILE 
( NAME = N'POS' , SIZE = 3048KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
GO
ALTER DATABASE POS MODIFY FILE 
( NAME = N'POS_log' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO
