Tips for naming variables
                                            
                                                - Make names as descriptive 
 as possible to help you remember the purpose of the variable.
- Eventually, you may have 
 hundreds of variables, so it is important to use a consistent naming scheme 
 that helps you find them in a list. 
- Variable names are case sensitive 
 (Sage Estimating (SQL) distinguishes between upper-case and lower-case letters).
- For readability, enter variable 
 names using initial capital letters.
- To set up a variable that 
 requires a YES or NO answer, end the variable name with a question mark 
 (?).
