He also said that if you have a function that is larger than one to one-and-a-half pages then that function could probably be broken down into separate functions itself. My rule is that if I have to type the same couple of lines over and over again then its time for a sub-routine or a loop. Functions are a beautiful thing that assist in the creation of your program and allows for brevity and ease of maintenance.
