Variable Naming Rules

Variable names can be composed of letters, dollar signs, underscores, and number signs. No other characters can be used. A variable name must start with a letter, after which any combination of the allowed characters can be used. The maximum length for a variable name is 30 characters. Variable names, like those of keywords and other identifiers, are not case sensitive.
