If you move your code from a notebook to a .m file (often known as a 
package file, but the code does not need to be a package), you will be 
able to execute the code by calling Get.

Since version 6, .m files edit inside Mathematica beautifully - you can 
even have headings in the code (which are stored inside the .m file as 
special comments) - it is easy to forget if you are editing a notebook 
or a package file.
