#### Combined operators

Combined operators

<> | Not equal |

!= | Not equal |

NOT | Not equal |

<= | Less than or equal to |

~> | Not greater than |

>= | Greater than or equal to |

During logical evaluation, any non-zero numeric value or non-blank string value indicates a true condition, and a null (blank) string or zero numeric value indicates a false condition.

Example:

Logical Expression Result

A = B | True when A is equal to B |

A < B | True when A is less than B |

A > B | True when A is greater than B |

A <> B | True when A is not equal to B |

A >= B | True when A is not less than B |

A <= B | True when A is not greater than B |

NOT A | True when A is null or zero |

A AND B | True when A is true and B is true |

A OR B | True when A is true, or B is true, or both are true |

A XOR B | True when A is true or B is true, but not both |
