A complex condition is formed by combining simple conditions, combined conditions, and/or complex conditions with logical operators, or negating these conditions with logical negation.
Each logical operator must be preceded and followed by a space. The following chart shows the logical operators and their meanings.
| Logical Operator | Name | Meaning |
|---|---|---|
| AND | Logical conjunction | The truth value is true when both conditions are true. |
| OR | Logical inclusive OR | The truth value is true when either or both conditions are true. |
| NOT | Logical negation | Reversal of truth value (the truth value is true if the condition is false). |
