LOGICAL_OPERATOR

Logical operators can be used to build more complex expressions.
The logical operators are:
Logical AND
Logical OR
Considerations
  • Two subexpressions joined by a logical operator form a logical expression.
  • Logical expressions resolve to a Boolean value: 1/0 or TRUE/FALSE.
  • Use parentheses--()--to group expressions logically and to join multiple expressions.
  • Parentheses are used in pairs; each open parenthesis "(" requires a closing parenthesis ")".
  • For example:
((<expression1> && <expression2>) || (<expression3> && <expression_4>))
