## Syntax

```
result = expression1 Or expression2
```

## Arguments

*result*

Any expression.*expression2*

Any expression.

## Remarks

If either or both expressions evaluate to **True**, *result* is **True**. The logical operation is not short-circuited. All expressions are evaluated.

The following table illustrates how *result* is determined:
