1. Introduction to sub-procedures and functions

Most computer programs are fairly complicated in the work they need to do. And so it is very important that the code is written in a well structured manner.

One of the key tools for producing neat, efficient, structured code is to make use of sub-procedures and functions.

This section will explain what these are and how to use them.

Spaghetti code

Code that is very poorly structured and jumps all over the place in a tangled manner is called 'spaghetti code' and is usually a nightmare to update and maintain. So avoid spaghetti code by following good coding practice as will be described in this section.
