	If you typed the above syntax sentence into ~~Business Rules!~~ exactly as it is shown, you'd cause an error (because it begins with the word “Line#” instead of an actual number). Only the words in capital letters (such as LET, which is called a keyword) and the punctuation marks (such as the equal sign) are meant literally while the words “variable” and “expression” will be replaced later with different values as you write your program.

	Business Rules! allows you to use either uppercase or lowercase letters when you type any command, statement or program. The system then takes what you have typed and automatically turns it into uppercase letters for you. (The exception to this is with literal expressions, which you will learn about in another chapter.) We encourage you to use whichever case (or a combination of both) that you are most comfortable with. You may also specify your preference of which case to use for comments, labels, keywords, expressions, etc. by entering these preferences into a style statement in your configuration file called wbconfig.sys. Here is an example of how this style statement might look:		Business Rules! allows you to use either uppercase or lowercase letters when you type any command, statement or program.

Mikhail.zheleznov: This question offers no benefit to the student. And how would one know where the missing keys would have gone on a keyboard if they are missing? They could be put on any button, so it would just be guesswork. I guess I just don't understand the question.

	Another important thing that you should know before you launch into programming is a little bit of information about statement syntax. Syntax is the word we use to describe the special order and punctuation that Business Rules! requires for commands and statements that you enter. You will see several syntax sentences in the lessons and chapters of this tutorial. They do not represent an actual command or statement; instead, they show you the general form of the command or statement in question.
