(or EXPRESSION EXPRESSION EXPRESSION ...)
An 'or' expression contains two or more expressions. They are evaluated from the left. If the first expression evaluates to true, the 'or' expression immediately evaluates to true. If the first expression evaluates to false, the next expression is considered. If all expressions evaluate to false, the 'or' expression evaluates to false. If any of the expressions evaluate to a value other than true or false, it is considered an error. Advanced Student Table of Contents
