Forth programming style

There is much written on the style of Forth programming and, indeed, there is book called ``Thinking Forth''[8]. Here are a number of recurring statements on programming in Forth that are relevant to sections of this tutorial:

• Build your application from the bottom up, testing new words as you go.
• Choose simple and meaningful names, so that the intent of each word is clear and your code is easily read, almost as statements you would make to another person.
• Always provide stack-effect comments.
• As you build your application, refactor your code aggressively so that you don't need complicated stack manipulations to access your data.
• Clean up after yourself and don't leave rubbish on the stack.
• Use the return-stack for temporary storage when it makes your code cleaner but be very careful to clean up when doing so.
