• Other characters can be letters, numbers or _
• Variable names are case-sensitive
• Variables should be all lowercase
• Words in a variable name should be separated by an underscore
• Don't start name with a digit.
• Never use special symbols like !, @, #, $, %
• Reserved words cannot be used as a variable
