The **OR** conditional operator evaluates an expression to true (-1) if any of the arguments is also true.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> [IF](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) and [OR](OR) numerical operations.

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

## Example(s)
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
a% = 100
|
||
|
|
b% = 50
|
||
|
|
|
||
|
|
IF (a% > b% AND a% < 100) OR b% = 50 THEN PRINT "True"
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
```text
|
||
|
|
|
||
|
|
True
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
> *Explanation:* The first evaluation was False, but the OR evaluation made the statement true and the code was executed.
