# OR (boolean)

Revision as of 00:31, 7 August 2013 by imported>Clippy

The **OR** coditional operator adds an alternative in a IF...THEN or Boolean statement.

## Syntax

- IF a = 1
**OR**a = 2 THEN a = 0

- IF a = 1

- OR adds an alternative to another conditional evaluation. IF True then the statement evaluation is True.
- Parenthesis may be used to clarify the order of comparisons in an evaluation.
- AND and
**OR**cannot be used to combine command line operations. **A duplicate OR OR statement will create a QB64 compiler error!**- 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 |

*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.
