The **OR** conditional operator evaluates an expression to true (-1) if any of the arguments is also true.

## Contents

## Syntax

- IF
*expression1***OR***expression2*THEN {code}

## Description

- OR adds an alternative to another conditional evaluation. If either element in the evaluation is true then the evaluation is true.
- Parenthesis may be used to clarify the order of comparisons in an evaluation.
- Not to be confused with the AND and OR numerical operations.

**Relational Operators:**

Symbol | Condition | Example Usage |
---|---|---|

< | Less than | IF a < b THEN |

> | Greater than | IF a > b THEN |

= | Equal | IF a = b THEN |

<= | Less than or equal | IF a <= b THEN |

>= | Greater than or equal | IF a >= b THEN |

<> | NOT equal | IF a <> b THEN |

## Examples

*Example:*

a% = 100 b% = 50 IF (a% > b% AND a% < 100) OR b% = 50 THEN PRINT "True"

True

*Explanation:*The first evaluation was False, but the OR evaluation made the statement true and the code was executed.
